Excessive Server Load

  • Hi everyone,

    My blog has been experiencing intermittent downtimes this past week and it’s using a lot of system resources.

    When I disabled the W3tTC plugin, the server load went down significantly.

    When I enabled the plugin, the server load went up again.

    I’ve setup W3TC to use Memcached on all caching features except for Minify.

  • Try disk enhanced for Page cache. Caching pages in memory could bring your resources to an end especially if you’re short on RAM. You can use memcache with db/obj cache.

    Thanks! I just tried what you recommended and the server loads did not go down.

    Tried putting everything on disk as my webhost support has told me that memcache was taking up quite a lot of memory but the server load still remains high.

    This is weird considering that W3TC is intended to lighten the load on the server. The last thing I will try is to completely disable the plugin to see if it will help.

    What hosting environment are you on?
    What version of W3TC have you installed?
    You should delete the w3tc and its configuration, install the development version and stick with the default options for a while and see how it goes.

    I’m running it with 512MB RAM VPS and memcache without any problems.

    I’m on a ServInt VPS, running CentOS 5 and 768MB of RAM.

    Using W3TC Version 0.9.2.1. How do I get the development version of the plugin?

    Get it from here:

    I’m now using the development version of W3TC but the server load randomly spikes then goes back to allowable levels.

    This issue propped up just last week, which is weird considering that I’ve been using this plugin for almost 4 months now without any issues.

    Tried the latest release?

    Yes. I was using the latest version I reverted to the development version.

    So far, it has brought down the server loads compared to before. But the loads are still high to warrant some concern because if sustained, it brings the server down to a crawl.

    Please try the latest update and let me know if there are issues.
