This morning I applied p3 and it's running, we'll see how long it goes.
I turned the access_cache_timeout on the 10 client systems down to 0.
I'm pushing about 35 Mbit/sec of traffic both ways at the moment. At
this point the clients are generating nfs server not responding/nfs
server is alive again messages every few minutes so if p3 doesn't fix
the issue I should see something. (I don't think the error isn't coming
from the disks. The FC disk array has plenty of spare capacity as
measured through gstat's %busy, mostly from having 4 GB of memory, most
of it Inactive).
Unfortunately the crashes produce no output at all, just hard hang. If
it continues I'm going to turn off SMP and go single processor. I
understand that may help get some useful output from a system crash.
Do you have any thoughts on hyperthreading on a system that's used only
as an NFS server?
