sbwait indicates a process is waiting for data on a socket. lockf indicates that a process is trying to lock portions of a file. If you put the two together, a cause could be network congestion (disk to network) or harddrive problems (network to disk). A server running out of memory and into swap can also be a cause, as processes are blocked (sockets don't get data and locks are not acquired) until the swap operation is completed. When processes keep getting spawned, this effect snowballs. -- Mel Problem with today's modular software: they start with the modules and never get to the software part. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
