Chat Plugin resulting in (104) Error – mod_fcgid: error reading data from FastCGI server, referer

Hello, I’ve been having some constant website malfunctions, often resulting in a timed-out connection or error 500. Been reviewing logs / trying different things, I don’t know how many different causes there are, but one that definitely is contributing in a big way is the Chat Plugin.

Error messages:

[Thu Apr 28 14:06:48 2016] [warn] [client IP] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://chat.example.com/example-page/

[Thu Apr 28 14:06:48 2016] [error] [client IP] Premature end of script headers: php, referer: http://chat.example.com/example-page/

This happened exactly as I was trying to open/close/clear a chat.

Now I honestly don’t know if this is something on the server/hosting side, or if it’s something happening within the plug-in itself.

The other plugin that may be contributing to this is Defender. When I first installed it, it ended up preventing the Chat plug-in from working. I’ve since deactivated it, but some of the ‘hardening’ activities may have changed back-end functions that now, even while deactivated, have effected how everything else functions.

I’ve been in contact with my server hosting, to see what insight they can provide, but also wanted to know what memory leaks there might be from the Chat plugin, or what other changes Defender might have made that would effect the PHP processes/reading information from FastCGI. Thank-you.
