I've read so it is hardware problem. As it start crashing when swap is used, it may be not memory but chipset problem - works fine until disk I/O is used. ___ 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
