OS: RHEL 7.6
Apache2.4.6 with FastCGI mod_fcgid/2.3.9
I have RT5 running in a custom location and everything works (ish) although RT sometimes takes several minutes to return a page and sometimes I get the dreaded Error 500 Internal Server Error. I’ve read through the docs several times and can’t see what config changes I need to make to improve performance. From the email side of things, everything appears to be running well and cases are being created. It’s simply the web interface that is having the issue.
As per web deployment doc I have disabled mod_speling and mod_cache and have the prefork MPM mod configured.
My SSL virtual host includes:
ScriptAlias /rt /app/rt5/sbin/rt-server.fcgi/
Require all granted
AddHandler fcgid-script fcgi
Does anyone have suggestions where else I could look/investigate.
Unsure if the logs help. I saw similar messages when some files didn’t have the right permissions. As this is intermittent, I’ve ruled out permissions:
