Web GUI Unresponsive in pfSense 2.3.4

  • Hello!

    Currently I have a primary/secondary pfSense cluster setup using CARP - this seems to work really well. However, whenever I log in to the secondary node, in order to do updates etc. the web interface is not always responsive, or it becomes unresponsive after a few minutes. The primary node however seems to work perfectly.

    Both VM's are running on version 2.3.4 of pfSense, the secondary node has the following software packages installed:

    • Open-VM-Tools

    • openvpn-client-export

    • Shellcmd

    • snort

    • squid

    • squidGuard

    The work around seems to be log into the console and restart the PHP-FPM service, and/or the webConfigurator. Which I wouldn't mind doing if it was an occasional problem. But as it happens so frequently the web interface is not very usable.

    After restarting the PHP-FPM service, I see some nginx errors in the System > General log (attached).

    I lot of the threads I've seen on this issue seem to be quite old and reference lighttpd, which I think I am right in saying, has now been replaced with nginx.

    I've also read this thread https://forum.pfsense.org/index.php?topic=139126.0 which seems to suggest that snort is the problem. I have tried uninstalling snort, but the issue still seems to persist.

    Any further help or suggestions much appreciated.
