Issue symptoms

Sometimes PHP websites return Error 503 page when LiteSpeed is used; however, users are not reaching LVE EP limits.

Cause

The issue may be caused by CSF/LFD killing PHP processes. If you have it installed, then check the log:

grep -i kill /var/log/lfd.log

Resolution

To resolve the issue for good, the /etc/csf/csf.pignore file should be modified - add the processes to be ignored:

echo "exe:/usr/local/lsws/bin/lshttpd.5.1.13" >> /etc/csf/csf.pignore
echo "exe:/usr/local/bin/lsphp" >> /etc/csf/csf.pignore

And restart LFD service:

service lfd restart
