The system then kills the biggest process (well, not exactly, it uses some additional heuristics). You need more swap. My 16 MB 486 has 120 MB of swap (no, it does not page itself to death, it is just that I have a bunch of processes swapped out; the total working set is about 95 to 100 MB, but the active working set is usually under 20 MB. Hence, I get about 85% load for a standard job mix--the swap wait is about 10% which is acceptable for the intended purposes). /Marino To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
