    Hello,
    Each time I enable Memcache from the SiteGround Cpanel and in my admin area for http://yourtechadvisors.com, the site throws timeout errors on the front and back end of the site. I received this reply from a ticket on SiteGround.

    I was able to “resolve” the problem by disabling the SuperCacher plugin. It seems that the website generate so much date in the backend that it cannot fit in the server’s cache and the website goes down:

    I have debugged your WordPress installation and this is the error I got:

    9478 recvfrom(4, "SERVER_ERROR object too large for cache\r\n", 8196, MSG_NOSIGNAL, NULL, NULL) = 41
    9478 poll([{fd=3, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout)
    9478 write(3, "0\3SELECT type FROM y7ch7j_nf_objects WHERE id = 5", 52) = 52
    9478 read(3, "\1\1\1N\2\3def\16ytadvise_wrdp1\21y7ch7j_nf_objects\21y7ch7j_nf_objects\4type\4type\f-\374\3\375\1\20\5\3\376\2\5\4\4form\5\5\376\2", 16384) = 114
    9478 sendto(4, "get 444014434360bb60425877d5ey7ch7j_:transient:nf_form_5\r\n", 58, MSG_NOSIGNAL, NULL, 0) = 58
    9478 recvfrom(4, 0x3531db8, 8196, 16384, 0, 0) = -1 EAGAIN (Resource temporarily unavailable)
    9478 poll([{fd=4, events=POLLIN}], 1, 5000) = ? ERESTART_RESTARTBLOCK (To be restarted)
    9478 --- SIGTERM (Terminated) @ 0 (0) ---

    I have tried deactivating all plugins, deactivating mu-plugins, installing the latest version of the plugin again, and installing WordPress again.

    Any ideas?

    Thanks.

  • I have experienced a very similar issue. Sometimes “killing” Memcached from active processes helps to solve the issue.

    It would be great if SiteGround would look into this issue more carefully. As it is now Memcached is causing random timeouts (504 errors / 522 errors – through CloudFlare).

    Any recommendations beyond just disabling Memcached would be greatly appreciated from a fellow SG customer 🙂

    Hello,

    I have experienced a very similar issue. Sometimes “killing” Memcached from active processes helps to solve the issue.

    How do you do that? After I disable Memcache in Cpanel, I have to go delete the cache file in wp-content to, if I do not delete that file, the site will not load.

    I also uncovered another error.
    [23-Mar-2016 22:39:51 UTC] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/ytadvise/public_html/wp-includes/functions.php:3792) in /home/ytadvise/public_html/wp-content/plugins/sg-cachepress/class-sg-cachepress.php on line 335

    Thanks.

    Hello,
    It is all fixed, there were some database tables that were to big and that was causing the timeout. Deleted the tables and everything is working fine with Memcache.

    Thanks.
