If you can get mpd into a state where "kill -9" doesn't kill it, then that seems like a kernel bug to me, and so we should probably hone in on that first.. maybe we can come up with a simple test case, e.g. using the event library debug output, write a program that opens the same number of file descriptors, pipes, etc. and registers the same event handlers, etc.. -Archie __________________________________________________________________________ Archie Cobbs * Packet Design * http://www.packetdesign.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
