swap

[l@e]

Does anyone hit the swap exhaustion lately with the last version of Version: FreeNAS-11.3-U4.1
the system needs to force reboot to recover.

X10SLM-F / Intel(R) Xeon(R) CPU E3-1241 v3 @ 3.50GHz / 32 GB ECC RAM/ 1x 64 SATADOM-SL 3ME3 V2 boot drive

the FN is just for sharing over SMB and there are no jails or vm running on top of it, and it is replicating some datasets to another FN that is also updated to 11.3.-U4.1 but is not throwing this error.
the error started after updating from 11.2 to latest (in steps), the FN have been in operation with same setup for +2 years

any way to see what process was using it before the crash ?

Usually, FreeNAS never uses swap, so something is severely wrong on your box. I'd look carefully at all the logs in /var/log, starting a little before 16:00 on 8/6, to see what blew up.
