It looks to me that the kernel may be running out of KVM resources. There are a couple of possibilities here. Arnvid, if possible I would like to download your vmcore (the one you were using in all the debug output filed in the PR) and associated kernel.debug and investigate this here.

If you decide that it is OK to supply the core to me for examination please put it up somewhere where I can download it (via ftp or the web), in a place normally hidden from view, and send me a PRIVATE email that does not Cc: the FreeBSD mailing list with the URL where it can be found. -Matt Matthew Dillon :On Fri, 30 Aug 2002 09:52:02 -0700 - "Bruce A.
