I have an old SMP machine at work which sometimes does something similar during its daily housekeeping, where Apache and Nagios are bounced and a small MySQL database dumped. It sometimes appears to hang during the database dump. The debugger shows many processes waiting for UFS. I suspect that the problem starts several minutes earlier. All of the following help to keep the problem away: Upgrading from a several months old 5-STABLE to 6-STABLE. Inserting 60 second delays at various points. Disabling SMP. No core dump available (Mylex disk controller). My next diagnostic step will be a serial console. -- Adrian Wontroba The biggest mistake you can make is to believe that you are working for someone else. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
