I have got similar weird things.i I often see this in the logfiles: Apr 11 13:07:28 server kern.info /kernel: nfsd send error 55 Apr 11 13:07:28 server last message repeated 719 times Apr 11 13:07:28 server kern.err /kernel: Out of mbuf clusters - increase maxusers! Apr 11 13:07:28 server kern.info /kernel: nfsd send error 55 Apr 11 13:07:28 server last message repeated 21 times Apr 11 13:07:28 server kern.crit /kernel: 55 Apr 11 13:07:28 server kern.info /kernel: nfsd send error 55 Apr 11 13:07:28 server last message repeated 743 times Apr 11 13:07:29 server kern.crit /kernel: 55 Apr 11 13:07:29 server kern.info /kernel: nfsd send error 55 Apr 11 13:07:29 server last message repeated 743 times >From time to time the machine reboots without any other messages or console errors. This only appears on a machine with 3 network cards and heavy net traffic. What I found curiuos is the line: /kernel: 55. I have changed kernel options, network cards, memory, motherboard, ... no change. This is a 2.2.1 system which serves a lot of PCs. During the night everything is sane but when the PCs are running the dmesg fills with "nfsd send error 55" and occasionaly crashes occur. I have no clue where to start or what to change... -Andre
