1) one of server(NAS) running on NeApp and the other server(SAN) running on Hitach
2) the client running on FreeBSD
3) the client rebooting once or twice in peak time. ( there was no error log)
4) netstat -rm say
boardr4 /sayclub 1 % netstat -rm
885/2048/34816 mbufs in use (current/peak/max):
730 mbufs allocated to data
155 mbufs allocated to packet headers
581/1104/8704 mbuf clusters in use (current/peak/max)
2720 Kbytes allocated to network (10% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
5) I thought it's not mbuf problem.
could you help me once more I find out about this problem ?

1) Is the NAS running FreeBSD?
2) Is the client running FreeBSD?
3) Is the NAS rebooting, or is the client rebooting?
4) If it's a FreeBSD machine rebooting, what does the
"netstat -m" say, for several samples leading up to
the reboot?
If it's a FreeBSD box rebooting, you are probably running
out of mbufs for some reason (probably bad tuning for the
load you are putting on it, but also possibly a bug). If
it's a bug, everyone would be complaining about it, so it's
probably not a bug, it's probably tuning, if it's the FreeBSD
box.
