I believe the problem lays in a mechanism of memory freeing for the Jail subsystem. I'm running few jails with vnet/vimage + PF filter in each. Basically each jail is a small virtual router with simple nat (lan0->wan0 natting). Could you please tell me what other info should I collect and attach to this bug? Appreciated.
