Hello.
I have 2 opnsense firewall on 2 site differents with the same configuration.
8 Go memory. 60 Go Hard Drive
intel pentium dualcore
Opnsense 18.7.3

Squid i-icap clamd
After about 1 or 2 day all the memory is used. And causing crash of squid. I need to reboot them. I have proceded to the upgrade the last day to the 18.7.3 but the problem still present.
I have activate swap option. But in the log i see no swap disk available when squid crashing.
And the problem is on the 2 opnsense firewall.
if i desactivate i-icap and clamd squid crash about 2 day.....
I don't know where to find the problem. And i need squid and blacklist for the school...
thank's for your help

I can confirm the same that the swap is not getting used in the dashboard. No crashes for me. I upgraded about 12 hours ago to 18.7.3.
Mem util - 15%
CPU below 5%

128 GB SSD; 8 GB RAM, 8 GB SWAP.
