While running the 2.4.18-4smp kernel (RedHat), and testing NFS3, our =
NetApp filer running OnTap 6.1.1R2 experienced massive incoming traffic =
from the Linux client in question. The Linux client required rebooting. =
We have been able to repeat this behavior, and are suspicious of the =
network driver on the Linux client which is using the eth0 driver. A

Sound familiar?

i'm wondering what are the common elements here:

is the EEpro 100 ethernet card common to all clients
that exhibit this problem?  NFSv3 over UDP?  what is
the nature of the network flood -- ICMP packets, or
UDP?  does "top" on the client show whether a particular
process or processes is spinning?

a tcpdump or at least "netstat -s" on the client after
the network is unplugged might be helpful.

ben-

were any patches applied to RH's 2.4.18 that touched the NFS client?
for example, were any of Trond's experimental patches applied?

thanks!

We have had a similar problem with NetApp F720 where couple times a day NetApp would stop responding. On one occassion we had an occurence where a single box was trying to write out a 2 GB core dump file to the NetApp which completely hosed it down. Even without misbehaving problems we had issues with it. We had a script from NetApp that was continuously doing sysstat, nfsstat but there were no indications on what was going on. This is all on a network of RedHat 7.2 clients with 2.4.9-31 RedHat stock kernel. What saved us was switching to NFS over TCP. I am not very fond of that particular solution since it is more like treating the symptoms and not the root cause.
