Why Does my Blog Keep Crashing with: [ERROR] Can not open directory for URI: /! (8 posts)

    My blog has just now for the fourth time in the past week broken with the same error. When it breaks I get the following message on the home page and I cannot log in:

    Index of /

    Name Last modified Size Description

    [ERROR] Can not open directory for URI: /!
    Proudly Served by LiteSpeed Web Server at http://www.mandm.org.nz Port 80

    The guy who does my hosting says there is nothing in the logs and that each time it is the same problem. I do not understand what he means when he says the following (but you might):

    the permissions of the main folder have been removed... and no one.. not even root can reset it.

    no one has access to public_html - which is where the files are.

    It might just be an anomaly, it could be a broken plugin in which case you'll need to work out which and disable it, let me ask the server guys first, to see if its server related.

    Well despite my hosting guy managing to get it backonline each time it has now done the exact same thing 4 times.

    The server guys say of the 50 WordPress blogs hosted on their server mine is the only one doing this. Hence my hosting guy says it must be either a plugin or something within my blog.

    My blog is at http://www.mandm.org.nz it is running on the latest version of WordPress. I run about 15 plugins:

    AddThis Social Bookmarking Widget
    All in One SEO Pack
    Block Top Spammers
    Broken Link Checker
    Easy Facebook Like Button
    Get Recent Comments
    Google Analytics for WordPress
    No Self Pings
    PayPal Donations
    Shockingly Simple Favicon
    Subscribe to Comments Reloaded
    TinyMCE Advanced
    WP Render Blogroll Links

    In the mean time can anyone give me some clues? Is there a plugin known to do this? Is there somewhere I can run my code through something to check to see if there is a bug somewhere? Help! Thanks :-)

    So your blog is fine for awhile when it comes back up and then it crashes? What do you do right before it crashes (if anything)?

    I'm not sure it is a plugin issue as typically once the plugin is activated it will already start displaying errors if there is something going wrong. But that is why I asked if after you perform any action on your blog the error shows up.

    The only thing we've noticed with the last 3 times it has crashed is that 6-8 people were actively commenting all at once. A lot of debate rages on our site, we can get threads with hundreds of comments, but normally it is spaced a bit, someone leaves a comment then 10-15 mins later someone leaves a response and so on... at the time of the crash we were noticing much more rapdid commenting, you'd reload the page and 5 new comments would be there, reload again and another few would be there - two of the times it crashed the comment frequency was up, more than normal - but surely it should be able to cope with rapid succession commenting - how do bigger sites cope?

    What type of hosting plan are you using? It is a shared hosting plan?

    From what you've said it sounds like a server issue as larger sites running WordPress are able to handle that many comments but of course the servers that they run on are optimized and made specifically for large volumes of traffic.

    If you can, try to find a time frame of when the last error was and write that down. Then get in touch with one of the tech guys from your hosting company and tell them to search the logs again within that time frame. They should see any potential issues popping up such as a plugin that could be overloading the server.

    I am not sure about the plan. It is a friend hosting it for us on a server he has access to.

    Twice it has crashed as I have been using the site so I was able to contact our host immediately, both times I have suggested the comment load and he did check but said absolutely nothing was in the logs.

    The amount of comments wasn't huge though - maybe in the space of 10 minutes 15-20 comments got left. Would that be enough to throw off a smaller server?

    No a standard WordPress install should be able to easily handle that even on the most basic hosting plan. I'm thinking its a plugin issue but hard to say considering the comment plugins you do have I don't see as causing a problem.

    When a plugin really dies it is easy to work out - you just turn them all off then turn then back on one at a time and load the blog after each one but this problem is trickier because after it crashes and gets revived it works again for a few hours or even a day or two then it dies again... much harder for me to test.
