logs
I am experiencing leaking of memory after few weeks of uptime.
After 30 days of uptime, wired memory is above 30 GB (of 48 GB of RAM).
PC is FreeBSD 14.0-RC2 amd64 machine with 48 GB of RAM with 2-3 VMs (with PCI
passthru), couple of Firefoxes, CAD, shells, editors, ...
ZFS ARC is limited to 2 GB.
Looking through vmstat output it seems that culprit is "vm_pgcache"
What is vm_pgcache?
How I can limit it?
The logs I have collected are in the attachment. They are collected before
rebooting the machine with VMs and most of programs shutdown.
Unfortunately I didn't collect all the logs but I will in month or so...
