I've run into problem that various prgorams (sendmail, ftpd) get often "cannot create socket: No buffer space available" error. Box is serving static html and images about 300 requests/sec, no shortage of memory nor CPU resources. Kernel is compiled with: maxusers 256 options NMBCLUSTERS=16384 and netstat shows following: # netstat -m 16634/25040/65536 mbufs in use (current/peak/max): 1318 mbufs allocated to data 15316 mbufs allocated to packet headers 1192/9452/16384 mbuf clusters in use (current/peak/max) 25164 Kbytes allocated to network (51% of mb_map in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines # netstat -an | wc -l 15207 My best guess is that system is running out of file descriptors. Any suggestions how to fix it? /fb To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
