Hi. We are running "NetApp Release 4.1cD3: Wed Jul 23 20:07:56 PDT 1997". Are you heavily using the NFS server? We had several hundred processes accessing the NFS filesystems when the problem started happening. With light load there wasn't a problem. Our fix was to go back to 2.1-stable and fix some bugs in that NFS implementation. The same bug fixes may help 2.2-stable but we don't have the luxury of being able to test that right now.
