Maxim gave me a patch that accomplishes exactly what I did by hand... but it also leaves it in a state that it was before 1.134 where there were some problems that were supposed to be fixed in 1.134 and after... however IMO its *less* broken :) Anyway, since my understanding of this is much less than anyone else I'm inclined to go with whatever solution actually makes the events trigger for us :) I'm not a kernel programmer, nor will I ever be, I just know that reverting uipc_socket.c did solve some major problems I was having :) -Trish -- Trish Lynch trish@bsdunix.net Ecartis Core Team trish@listmistress.org EFNet IRC Operator @ efnet.demon.co.uk AilleCat@EFNet Key fingerprint = C44E 8E63 6E3C 18BD 608F E004 9DC7 C2E9 0E24 DFBD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
