I mentioned before that I had a 3.0 machine locking up/panic'ing a lot. I wa sgetting lots of 'nfsd send error 55's, after some digging, that seems to be 'no buffer space available'. I don't know if NMBCLUSTERS= even has anything to do with buffering for nfs writes, but bumping that way up fixed my problem. I still get the very rare error 55, but the machine has stayed up 5 days now. One problem was that during heavy nfs traffic, the machine would keep running, but any attempt to read/write to a nfs file/directory would hang the process. I'm not sure what to look at when that happens, but while it was going on, i did a netstat -m. 1028 mbufs in use: 711 mbufs allocated to data 304 mbufs allocated to packet headers 11 mbufs allocated to protocol control blocks 2 mbufs allocated to socket names and addresses 554/1392 mbuf clusters in use 2912 Kbytes allocated to network (42% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines I'm using 3c509B's in all my machines. I only get nfsd send error 55's on both the machines when the one machine running 3.0 is active. Kevin
