Hmm. 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.
Please note that vmcore's may contain sensitive information such as
passwords and such, so it's entirely up to you/your-company to decide
whether to do this or not. 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.
