Is the problem SMP related? No, it has to do with running low on kernel memory and blocking, after recovering from the low memory situation it doesn't handle the changes properly. There's also problems with the socketbuffer code because of the chance of sleeping, the updates to the limit structures need to be atomic and this should do it: http://people.freebsd.org/~alfred/uidinfo.diff applies to HEAD. Brian, can you please review? thanks, -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
