Bjoern,

I was looking at this bug in FreeNAS:

"Panic on new jail with vnet"
https://bugs.freenas.org/issues/3102

It turns out that the root cause of the problem is the same as the
one mentioned here:

http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021280.html

Using the testcase in that mail, I can reproduce these error messages:

Freed UMA keg was not empty (10 items). Lost 1 pages of memory.

and eventually get a kernel panic.

In this message, you mentioned that you might have a patch which fixes the
problem:

By any chance, do you have a patch handy?  I can quickly try it out
and provide feedback.

Thanks.
