#define quoting(mwlucas@exceptionet.com) // We have a 2.2.8-stable box running IPFilter. This box keeps runninng out // of mbufs very quickly. // // We have a kernel (full config below) that includes the following lines: // // maxusers 256 // options "NMBCLUSTERS=4096" // // This should give us a whole heap of mbufs. // // A netstat -m, however, shows us: // // scooby# netstat -m // 136 mbufs in use: // 130 mbufs allocated to data // 1 mbufs allocated to packet headers // 4 mbufs allocated to protocol control blocks // 1 mbufs allocated to socket names and addresses // 128/132 mbuf clusters in use // 281 Kbytes allocated to network (97% in use) // 0 requests for memory denied // 0 requests for memory delayed // 0 calls to protocol drain routines Are you sure you did reboot with this kernel ? Even if options NMBCLUSTERS was wrong (and this is not the case), the default for 256 users is 512 + MAXUSERS * 16 = 4608 Jonny -- João Carlos Mendes Luís jonny@jonny.eng.br To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
