It was because there was a mbuf alloc that wasn't protected with at least splimp(). Remember that all the network driver interrupt routines will allocate mbufs and they run at splimp(), so all other places have to run at splimp() also. Anyway just a guess, it might not be your problem, but it was definitely ours. :-) John -- John Hay -- John.Hay@mikom.csir.co.za To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
