Running pktt on the netapp reveals LOTS of UDP nfs traffic to the filer but no responses from the filer. The client is a Red Hat linux box.
We are stumped on this at this point. Any advice?
I'll wager the client is running the 2.4.18-3 kernel that shipped with Red Hat 7.3. You can either upgrade to 2.4.18-10 (or even -5) or manually set the rsize and wsize mount settings to something reasonable like 8192.
