Hi,
we have a problem with one of our fileserver (NFS). The system is exporting
stornext file systems via nfs(3). After some weeks one of the migration processes
is starting to take more and more cpu time.
The system is working stable, but our nagios is getting nervous about a process taking
so much cpu time.
Some time ago this bug was posted:
https://bugzilla.kernel.org/show_bug.cgi?id=47341
But we have to identical NFS servers (same hardware, same software) and only ONE
is showing this behavior. However we can not change the kernel (-> stornext)…
Any idea ?
System: SLES 11 SP2, 3.0.13-0.27-default, x86_64
