As promised, here are the full logs (in attachment)
This is a serial console log showing the command loop that triggers the bug on
a debug kernel and ensuing DDB session.
the obvious problem line is :

(further tests showed an increase of the routetbl malloc zone by 4MBytes for
each vnet jail creation/destruction cycle)
