Hi,
One of my servers is hanging with memory exhausted. This happens whenever the ZFS system is "on", either by starting the service (rc.local or
This same system has been tested with ZFS system off, and the server keeps running with about 15 GB free memory for upwards of 4 hours.
The system worked correctly for over one month, with ZFS filesystem mounted and being served over NFS.
From my testing, the memory exhaustion occurs between 15 to 90 minutes after the ZFS system is started.
I've tested with setting vfs.zfs.arc_max and vm.kmem_size, but without success, although the longer 90 minutes period occurred with vm.kmem_size_max=15032385536 and vfs.zfs.arc_max=10737418240 (this being a 16 GB server, amd64).
Any hints/tips/pointers in the right direction so that I can diagnose this?
Thanks in advance,
