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. -- Craig
