[NETVIRT-1000] Transaction Leaks in neutronvpn, fibmanager & vpnmanager

Blocks — Mon, 20 Nov 2017 17:27:32 +0000

As found in ~~NETVIRT-985~~, here are transactions opened in netvirt itself which are apparently never closed, roughly sorted in order of importance, based on number of open TXs = likelyness to cause OOM: (The class line numbers refer to stable/carbon; and the list has already filtered out and omits leaks that are only a few lines apart which occur when several write transactions are opened together for separate shards incl. config/oper.)

493x transactions opened here, which are not closed:
