I'm using OPNsense 18.7.3 without swap (inside Proxmox if it matters) and I've noticed sporadic OOM kills. I've added more memory to fix the problem, but I still don't understand the cause of this problem.
Here's an OPNSense memory usage in percents:

~Every 24 hours there's a huge memory spike and I can't find anything in the logs. Any ideas what it can be?
i have the same problem.
but no vm.
All memory is used and causing service craching like squid.
Since squid has a rather large demand in memory (even with only a few rules) it could be that the spikes are from reloading the rules (or maybe other large tables/lists)..
I don't have squid. I have huge alias table, but it's reloaded every 8 hours and I can't see spikes at these intervals.
