  2. That said, if someone is having an issue, they are having the issue regardless of whether you can replicate it or not.

    @gilzow - please don't misunderstand, I totally agree there's an issue. But you understand the difference between "there's a problem with WordPress" and "there's a problem with my implementation of WordPress." For non software folks, that probably sounded totally annoying semantic, but there's a difference. It's like saying "There's a problem with Nike Shoes" and "There's a problem with how Nike Shoes fit my feet." Both are valid issues with Nike, but they're very different issues. Nike, nor WordPress, can always work 100% the same for everyone, because people are never 100% the same. (Extend the metaphor, and your feet aren't actually the exact same size/shape, unless you're Daniel Dae Kim who is freakishly symmetrical, and that's why you don't always get the same results when testing the 'same' setup in a different location.)

    Philosophy aside, how big are your multisites? I ran a scheduled post this morning, and my CPU spiked to 0.89 (normally it's around 0.1), which is the same as a manually posted post for me (different site on the same network). I'm also using domain mapping on the site with scheduled posts.

    To answer your question @Ipstenu, yes, all of these sites are on the same "server" (3 virtualized servers behind a physical load balancer, all attached to NFS). And I too am beginning to wonder if the root of the problem lies with this configuration. When I cloned one of the sites over to our development server (a single non-load-balanced server), there were zero issues with the scheduler. Even if I changed the timeout in cron.php back to the default of 0.1 it worked correctly.

    Are you seeing any HEAD requests for wp-cron.php in your error logs with a 403? And what's the load balancer of choice? I have a vague recollection of squid needing to be kicked.

    I don't see any common plugin with gilzow.

    I do see that Doug Hardy mentioned domain mapping... and I do see that we are all using Multisite...

    @Gilzow, re your question:o you know any specifics on how your bluehost server is configured?

    What do you need to know exactly. I am not as techy as you :-( I didn't do any specific set up (just using Bluehost in its standard set up).
    If you tell me what I should look for, I'll go check in my Cpanel.

    Thank you.

    I'll have to request the logs from the sysadmins when they get back on wednesday (i dont want to make the on-call person have to deal with this on new year's eve), as I dont have access to them. I'll let you know. If memory serves me correctly, the load balancer is a Nortel/Avaya 2424-SSL.

    Yeah, I'm not seeing any CPU spikes either.

    @Sarah974, one of the sites that I'm seeing issues with is a single wordpress install, not a multisite. And I have a separate multisite install that isnt having issues. As for host configuration, if you are using bluehost's standard configuration, then you probably dont have anything odd/unusual going on.

  5. Yet Another Related Posts Plugin tends to cause CPU spikes when you post, since it has to relate all the posts.

    Akismet, Jetpack, W3TC, and WPMU Domain Mapping are all very common plugin sets to have, and I would expect more people to have the problem if it was them, or even the combination thereof. I'll tag this for Bluehost. I know their WP Guru, maybe he has an idea or can poke.

    gilzow - I have a gut feeling that if anything, the balancer or your firewall is hamstringing wp-cron, and possibly not permitting files to call themselves.

    But the question remains: why with 3.5 and not the other versions?

    Thanks for hanging in there with us :-)

    Hey guys, I've read all the replies.

    Something similar is happening with my WordPress install. I did upgrade to the 3.5 version and everything was working smoothly. Two days ago something happened and now the posts are not being posted.

    I'll try some of the things you've posted and I'll let you know.

    If someone finds the solution, please post it, I would really appreciate it :)

    Cheers.

    I am also facing the same problem after upgrading to 3.5 for all my sites. Could it be a problem with the hosting because i have contacted a friend blogger with same hosting and he is also facing same problem?

    @muhammad irfan - yes. If you want the scheduling feature as of now - reverse to prev version. As Sarah974 tested, the prev version isn't facing any problem with scheduling.

    I am also facing the missed schedule bug on WP 3.5.

    @Ipstenu, I would be inclined to agree with you except that I have two other installs (one multisite/network, one single) on the same "server" that aren't having any issues at all with the scheduler. Now granted, scheduled publishing isnt used on those two sites very often, but every time I've scheduled a test post, it has worked.

    Regardless, the sysadmins are back today and will send me the logs as soon as I set up another scheduled post. Will post the results of those logs as soon as I have them.

    ok, we scheduled a post, watched it fail and then checked the error logs. Nada. Nothing at all for the account during the time period when the post was scheduled to post, and I was visiting the site in a different browser in order to trigger the cron.

    I installed the fix plugin, but I'm very interested to hear a resolution for this problem. It is a WordPress core issue, so fingers crossed.

    I've been having the same issue with missed scheduled posts.
    After manually deactivating and manually testing each plug-in I've discovered that the only plug-in that the missed schedule fault happens with for me is "w3 total cache".
    Deactivating that plugin does appear to have allowed posts to be published at the scheduled time.
    I notice that although that's a plug-in that's listed on some of the lists above, it's not on all but my technical knowledge is reaching it's edge to offer anything more than these observations.
    Hope that bit of extra info helps identify what the route cause etc :)

    If any of you have been having problems with this and you have W3 Total Cache activated (and updated), try deactivating it.

    It worked for me.

    We are experiencing the same "Missed Schedule" issue on one of our sites since upgrading to 3.5. Our other four sites running 3.5, on the same VPS, are not experiencing any missed posts. I've doublechecked the plugins we're using, and don't see anything different on the erroring site than what's on the functioning sites. I'm stumped!

  17. W3TC just updated. Try the new version? I'm using it and it's just fine, which is why this is very vexing to everyone :/

    I really feel that since a smal (smaaaall) number of users have this issue, it's got to be a combination of plugins + WP 3.5 changes + server. It's the only thing that makes logical sense.

    Now at last I figured out the culprits. and they are

    W3 Total Cache Version 0.9.2.5
    WordPress SEO Version 1.3.4.1

    Deactivate both of them and scheduler problem is resolved. At least it worked for me.

    I have just seen a missed scheduled post since upgrading to 3.5.

    I do have WP SuperCache and it is throwing pre-load errors, so perhaps that is causing it for me.

    I have manually installed v3.5 with no plugins or themes to see if it can schedule posts correctly.. Unfortunately it does not. So in its simplest form, it appears to be broken.
    However, this leaves me with a completely fresh dev site should people with know-how want to assist me and look at the mechanics behind the scenes with me...

    Volunteers (with sound idea's to resolve this) get to log in as admins to the WP site only... I will retain access to the backend/ftp area...

    I upgraded to 3.5 and I don't see scheduled posts in the cron events list, and they aren't getting posted at all. I have a ton of plugins, but W3TC was disabled while I tested this.

    I disabled all of my plugins, including

    W3 Total Cache Version 0.9.2.5
    WordPress SEO Version 1.3.4.1

    and posts are still missing schedule.

  23. Phil Broughton - Server specs please? :) What version of PHP are you running and what flavor (FastCGI, DSO, etc)? Do you have server caching (APC or xCache)? Apache or nginx?

    @Mika - I have raised a fault ticket here : http://core.trac.wordpress.org/ticket/23133 to follow this through as well.

    I have exposed the php.info and server information here (password required, find me on facebook for a private chat perhaps!)

    http://dev.crinniswoodmanagement.co.uk/

    MYSQL details (obtained from phpMYAdmin on 8th January 2013)

    Server: Localhost via UNIX socket
    Software: MySQL
    Software version: 5.5.25a-log – MySQL Community Server (GPL)
    Protocol version: 10
    User: xxxxxx@localhost
    Server charset: UTF-8 Unicode (utf8)
    
    Server Web Software:
    Apache/2
    PHP Software:
    PHP Version 5.3.10 / Server API	"CGI/FastCGI" / 20090626

    Not sure how to check server caching is in play...

    Now updated to WordPress 3.5.1, does scheduling work? Anyone checked ?

  26. Phil Broughton

    I have and the 3.5.1 update has no fixes or adjustments to assist with this fault. I have a developer offering his services to assist with the fault I raised, but not being a paid developer this is being worked on a voluntary basis. So be patient and hope this can be resolved. Personally I want to see more debug switches and a better FAQ on the topic which has been pretty minimal in recent times.

    The issue is solved after today's update on W3Total cache.

    This plugin http://wordpress.org/extend/plugins/wp-missed-schedule/

    When it picks up the missed post while using Jetpack it breaks the social autopost function of publishing to twitter, facebook, etc have to delete the post republish manually so basically worthless if using jetpack

    I cannot schedule a post since upgrading to 3.5.2. I'm not a computer person so I have no idea how to fix this. Do you have an easy to follow fixit solution?
    Thx
