How much swap do you have? You might have run out of buckets in the swap_zone before you ran out of swap space, in which case the kernel deadlocks rather than killing the hog like it does when it runs out of swap space. I added a printf to catch this on HEAD recently that will be MFC'd soonish. You can try bumping up kern.maxswzone (loader tunable). -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
