Hi! We have a lots of FreeBSD based routers in our network, and after upgrade to 2.2.6-RELEASE we reach problems with some of them. Sometimes intensive-loaded interfaces refuse to work, and when I try to ping some hosts throw affected interface I got 'no buffer space available', with mbuf usage (according to netstat -m) no more then 60%. In most cases problem affect routers with interfaces working on different speeds: phbme -- ed0, ed1, ed2 -- NE2000 clones working on 10Mb/s, de0 -- DEC-based working on 100Mb/s ptf -- ed0 -- NE2000 clone working on 10Mb/s, de0 -- DEC-based working on 10Mb/s, sl0 -- slip interface working on 115.2Kb/s (no hardware flow control). but sometimes it also affect routers with interfaces working on the same speed (also 2.2.6-RELEASE). All hosts kernels are builded with 'maxusers 64'. -- Regards, Vladimir. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
