I'm going to try some assuptions here: a) you're running 2.2.x and haven't upgraded to 3.x means that you are experiancing this problem on a production box that you can't upgrade. b) you really don't care about the crashdump, you just want the box to stop rebooting. :) I would take the advice given by the kernel, increase maxusers and compile a new kernel, if maxusers is already very high you may want to fiddle with NMBCLUSTERS, do a search of the mailing lists for NMBCLUSTER guidlines. > I believe I've followed all the necessary steps to ensure a dump.

If you could I would at least upgrade this to a 2.2-stable release using cvsup set your tag to RELENG_2_2 for your source dir. -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
