We have a machine running FreeBSD 2.2.7 that is our database/NFS machine. It holds our user home directories that is NFS mounted to all the machines. Our database is running on it and we have a file server for a large game running on the box. It periodically reboots with a message saying "out of mbuf clusters, increase max users". The machine is not stressed in file io, memory usage, or CPU usage. We build a new kernel with more max users and we still get the crash. At one point we hade maxusers at 512 and we still got the error (it happend under 2.2.1 and we upgraded to 2.2.7 to see if it fixed the problem but it didn't) On a possible related note, many of our machines get these messages which pop up on the console which say that the NFS on this server went away followed by a message saying that it is back (I don't have the exact text with me since I just got paged out of bed because of the reboot). We have about 20 nfsiod's running on the server to deal with the increased traffic. One other symptom. These .nfsNNNNN.4 files are left laying around all the time. I think we don't understand something about NFS and it may be the culprit to our mbuf issue which is my primary concern since it is currently crashing us. Any help would be appreciated.
