List-Post: List-Help: List-Subscribe: , List-Archive: I have a 2.6.11.5 NFS server that serves a directory /s that had light to moderate activity. I had another file server mounted as /nicfs7 and was doing a local rsync (moving some data) from /s/path to /nicfs7/path when (for some unknown reason) it hung. I hit ctrl-c and then kill -9'ed the two remaining rsync processes. I then unmounted /nicfs7 (which seemed ok right after). I then saw what I pasted in below in messages. At this point NFS service seems ok; however, one of the nfsd threads is missing. I specify to start 128 and only 127 are running. Is a missing nfsd a problem? It's no clear to me why an nfsd did in the first place either when I was using nfs client -> local disk.
