Adrian,

As part of looking at this bug in FreeNAS:

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

I started looking at this thread:

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

Based on this clue from Thiery:

http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021291.html

I fixed some VIMAGE related memory leaks related to routetbl.
I also fixed some VIMAGE related kernel panics when
I tried creating and deleting lots of jails:

http://lists.freebsd.org/pipermail/svn-src-all/2013-November/077178.html
http://lists.freebsd.org/pipermail/svn-src-all/2013-November/077192.html
http://lists.freebsd.org/pipermail/svn-src-all/2013-November/077195.html

I haven't eliminated all the "Freed UMA keg was not empty"
error messages.

Do you have any recommendations for how I can track down the last
few UMA related memory leaks?  I am new to debugging UMA so
would appreciate any pointers that you may have.
