For i386 I'd be more inclined to suspect KVA exhaustion. For non-PAE, as a shot in the dark, increase options KVA_PAGES=384 .. the default is 256 for PAE. that increases kernel KVA from 1GB to 1.5GB. For a PAE system, this number is multipled by 2, so a corresponding change is 512 -> 768. This is just a shot in the dark. If this is amd64, then never mind, KVA_PAGES is meaningless there. -- Peter Wemm - pe...@wemm.org; pe...@freebsd.org; pe...@yahoo-inc.com; KI6FJV On IRC, talking about C++: <BigKnife> I think that it is a good thing I will never meet Bjarne on a street <BigKnife> cause really, I don't want to end up in prison or anything _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
