Frequent Restart of PHP/FPM During HA Failover 7100
-
We have two 7100s setup in HA for our primary firewall. While performing maintenance tasks (entering CARP maintenance, rebooting the primary, exiting maintenance) we often encounter an issue where parts of either the primary or secondary to not function or view as expected in the webGUI.
These issues specifically manifest as no webGUI at all, various services not reporting or reporting as down in the webGUI, and various other visual issues as well. The only resolution we have had success with is logging into console and restarting PHP/FPM.
We see this happen when switching masters during failover, sometimes on the one becoming backup, sometimes on the one becoming master. Most frequently we see it happen on our secondary device when we swap it back to backup from master - the webGUI will fail entirely.
Is this a known issue? Or do we potentially have a misconfiguration somewhere? Just looking for any better mitigation steps than SSHing into console all the time.
Thanks!
