I can reproduce the problem, but it doesn't cause a panic. : :Dave. :|David Gilbert, Velocet Communications. | Two things can only be | You need to figure out what the processes are locked up in. If 'ps axl' doesn't work then you need to ctl-alt-esc into DDB (assuming the kernel is configured for DDB) and do a 'ps' there. It should be possible to narrow the problem down from that output. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
