WordPress V4.4 wp-includes/plugin.php memory leak?

    9 years, 3 months ago

    PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 32 bytes) in /arcs/reswp/silverbullet/wp-includes/plugin.php on line 202, referer: https://silverbullet.newcastle.edu.au/victor/about-me-4/

    Could this be related to this plugin not being compatible with wordpress V4.4?

    If I increase memory_limit in php to 512M plugin.php is still not happy and I end up with a huge load average, segmentation fault and zen cache errors in apache log and kernel memory errors in messgaes. increasing cpu cores and memeory in sever makes no difference so I cannot make this plugin.php happy.

    It is only this particular wordpress site that does this and I can see NOW this has been happening since at least V4.0. Other multisites are OK but do not use this plugin and biggest is 45 multisites sites and different server but same OS, OS packages. They started identical one a clone of the other.

    This is a WP SITE I took over into OUR Enterprise RHEL 12 months ago.
    It had been running for years at our uni on a BSD unix server that was not patched and neither was wordpress patched so security found too many vulnerbilities. There are 904 multisites at the moment. There are 76 plugins only 9 active (4 of these not compatible with V4.4) SITE Admin not responding to phone or email. I have to keep the server and server apache working because there are other SITES on the server.

    I have to patch wordpress to the latest version or security will want the SITE shutdown.

    Why do you think it’s this plugin specifically? Does deactivating it solve your problem?

    You should consider throwing up https://blackfire.io/ on your server and do a proper code profile to determine the exact source of your memory leak.

    THANKS for your reply.

    A bit out of my depth and had to give up because we had too much else on and too many people away.

    I did not try deactivating the plugin yet.

    I have not been able to get any response from the wordpress site administrator.

    I will organise to deactivate your plugin and see what happens and I will take a look at https://blackfire.io

    There is more than 1 wordpress site on this server.
    This is the only Site that is doing this.

    I settled back to these changes to php defaults.
    They are in .htaccess and you can see in apache logs that they apply to this WP instance.

    I had increased memory_limit up and up to 2048 to see a lot more Kernel out of memory in the messages files.

    max_Execution_time is also reached in comment-template.php line 1337 frequently.
    I increased the limit up to > 10 minutes and max_exection_time FATAL error still happens.

    php_value upload_max_filesize 999M
    php_value post_max_size 999M
    php_value memory_limit 256M
    <IfModule mod_php5.c>
    php_value max_execution_time 60
    </IfModule>

    When I look at PERFORMANCE NOW CPU is 99 or 100% out of 8G 2.4G used 5.6G free.
