Hello.
OS:
# uname -a
FreeBSD devel.ucsnet.ru 4.8-RELEASE-p13 FreeBSD 4.8-RELEASE-p13 #9: Wed Nov 26 12:38:10 YEKT 2003 root@devel.ucsnet.ru:/usr/src/sys/compile/PAVELSH_DEVEL i386
Problem - error message "No buffer space available".
But,
# netstat -m
145/18656/32768 mbufs in use (current/peak/max):
144 mbufs allocated to data
1 mbufs allocated to packet headers
142/628/8192 mbuf clusters in use (current/peak/max)
5920 Kbytes allocated to network (24% of mb_map in use)
25 requests for memory denied
1 requests for memory delayed
0 calls to protocol drain routines
Peak was 18656, max 32768. Why i'm got message "No buffer space
available"?
P.S.:
