next in thread | raw e-mail | index | archive | help
Hello,
Recently I updated my RELENG_8 to RELENG_9. Since then, the server hangs
from time to time for 5 minutes. When I run a top in a remote terminal,
I can see that it hangs so strong, that the clock hangs too. When it
continues to run , the time continues from the when it 'hanged'. TCP
connections are also dropped with timeout at that time. However, no
kernel panic, and i can't see anything in the dmesg log too.
A strange thing is, the server continues working when I press a key at
the physical console (I'm doing this with a remote IP console). More
strange thing is, when I do a reboot, the server flushes all its disks,
and then does a panic, instead of rebooting.
I have to revert to the RELENG_8 kernel (userland is RELENG_9 now), I
have no other choice.
I hardly can get the configuration and log out from it these times,
because of the hangs.
Hardware details:
This has 4 SAMSUNG disk (1.5TB each) array, driven by a 3ware Raid
controller, each disk exported as is. It also has an OCZ Revodrive as a
disk cache (zfs L2ARC cache) limited to SATA1 speed (strange kernel
panics because of disk timeouts when using at full speed), 8GB RAM,
AMD64 processor.
FreeBSD details:
The server runs on the 4-disk zfs array, boots from it and uses the zfs
array also as root media. It has 4 jails, connections handled by pf.
