List-Unsubscribe: , List-Archive: 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.
