We did a desperate upgrade to CURRENT in hope that this would fix the problem ;)
The machine became much faster but as soon as we put some load on, it panics but
still responds to ping. There is nothing in the logs after a power cycle.
Is there anything we can do to help troubleshoot this, would a DEBUG-kernel
help? We can supply ssh access if that would make it easier.
The load that causes this is a MySQL import over the network, a lot of CPU, disk
access and nfs. The machine panics after 30-60 minutes into the import.
The only thing the logs says is
nfs.server:/storage/vol1/export: inaccurate wcc data (ctime) detected, disabling
wcc (ctime 1214902261.000000000 1214902261.000000000, mtime 1214902261.000000000
But that is when I mount the volume.
