Debugging OPNsense service drops

[standard_count]

I've had a few occasions recently where traffic through my OPNSense server has dropped due to some sort of OPNsense freeze, and I need help debugging this.

Code: [Select]

Versions:
OPNsense 23.1.4_1
Running as a VM on Proxmox 5.15.83-1-pve

Behavior:
Network traffic stops
Web GUI not accessible

I recently upgraded to 23.1.4_1 in the hopes that it would fix this, but no luck.  The web interface does not come up, but I am able to get into the server via the console.  I'm not seeing anything obvious in the logs.  Choosing "Reload all services" fixes network connectivity.  "Starting web GUI" failed on service reload the first two times, but it started the third time.  Service reload pauses at "Starting eastpect.".  I need to hit control-C to get back to the main menu.

Browsing around the logs doesn't show anything obvious, except that I get a few messages like this in the system.log:

Code: [Select]

Can someone give me pointers on how I could debug this?
