  • More sites recovered – TSOhost yet to apologise

    It appears that my problem with this site was not a one-off. Quite a few of the sites that I have hosted with TSOhost were affected by the server switch. For some reason during the migration the level of PHP that was chosen was 5.4.45, with memory_limit set to 25M.

  • Site recovered – sorry for the inconvenience

    Sometime on the 12th my site started to produce a series of PHP Fatal errors saying “Allowed memory size of 41943040 bytes exhausted.”. This was a bit of a surprise. It means that my memory limit was 40M, a lot lower than the expected value of 256M. Other times the response was

    [13-Jul-2016 02:54:59 UTC] PHP Fatal error:  Unknown: 
    Cannot use output buffering in output buffering display handlers in Unknown on line 0

    Problem recovery

    To recover from this problem I used ftp to rename Jetpack to Jetpack-f. I was then able to access the site.

    Problem explanation

    • The site was migrated from one host to another.
    • The PHP version on the new host was 5.4.45.
    • The memory_limit was set to 25M.
    • For PHP 5.3, 5.5 and 5.6 the memory_limit would have been 256M; a much nicer number.
    • By the time WordPress started up the memory limit became 40M.
    • It’s WordPress that sets this limit, depending on the site. For WPMS it’s 64M. See wp_initial_constants().
    I’ve yet to track down the specific plugin/module combination that causes WP to exceed the 4OM limit.

    Other notes

    • My oik-bwtrace plugin reports the memory limit on its admin page.
    • This is 256M, since WordPress sets it higher in admin pages. Using admin_memory_limit in wp-admin/admin.php.
    • I’ve changed my [wp] shortcode to display the memory limit on the front-end.
    • For this site the memory_limit has already been set by the hosting company to a high value.
      WordPress 5.8.3. PHP: 7.3.33. Memory limit: 768M
    • I’m also experimenting with code that displays the current memory_limit in trace records produced by oik-bwtrace. They already optionally display current and peak memory usage, so adding the current memory limit is no big deal.
