I tracked this issue down a little.
I put some printf's and found that this occurs in the function
vnet_destroy() in sys/net/vnet.c.
The memory leak seems to happen when vnet_sysuninit() is called.
So, something needs to be done before or inside vnet_sysuninit(), but
I do not know
what to do.
The messages I saw on head and stable/10 around 2014-04-30 are:
Freed UMA keg (udp_inpcb) was not empty (135 items). Lost 9 pages of memory.
Freed UMA keg (udpcb) was not empty (250 items). Lost 1 pages of memory.
Freed UMA keg (tcp_inpcb) was not empty (75 items). Lost 5 pages of memory.
Freed UMA keg (tcpcb) was not empty (15 items). Lost 3 pages of memory.
