W3 Total Cache
Site crashes or Infinite Load after making new post (5 posts)

    Alright so i have the latest version of w3tc

    First I would like to ask a question. What exactly happens whenever I make a New post on my wordpress. Does w3tc try to delete all cached and refresh?

    I use APC with 512mb given to it. This usually fills up in about 2 hours, then for 1 hour the Cache full count will increase and finally on the 3rd hour, my apache will restart.

    I have a cron job to restart apache every 3 hours.

    Anyhow, so what I notice is.....if I make a post between the 2nd/3rd hour, when APC 512mb is filled up....it seems that when w3tc tries to do it's thing (clear the Memory i believe) it locks up or crashes the site.

    Then I have to manually go through ssh and restart apache.

    Any solution to this problem ?? This problem may be unrelated to APC for all I know...

    my website is: animefushigi . com and the apc settings are just /apc.php of the domain.

    If it helps, I would like to add that my server load goes down to 0.4 when this all happens. Usually server load is 1.5-3.0

    When you edit a post or receive a comment on it, it is updated.

    Why are you restarting apache? Why do you need 512MB of SHM allocated to APC? It seems you have server configuration issues. Your average server load is pretty high to have caching running. So either W3TC is misconfigured or your server stack is also.

    I am restarting Apache because my 512mb allocated to APC fills up really quickly, and from then it it's just increasing the Cache Full Count, which causes my site to crash after some time.

    I use 512mb of memory because a smaller amount would not be enough, even 512 is not enough.....

    Average load has always been like this. I got a quad core so anything below 4 is good I think.

    I think I helped you with your server finding a theme file that was highly inefficient that could not be saved by caching.
