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:

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/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.
