Sorry just to make sure no misunderstandings - does this specific first comment refer to the (old, I just made a typo) Bug 7370 (fixed a while ago in openflowplugin) or my new Bug 9034 ? Robert> Actually no. The backend side of things looks okay, as chains are being both closed and purged when requested from the frontend. I suspect somebody is forgetting to close their transaction chains...

I did stumble upont something - could https://git.opendaylight.org/gerrit/#/c/62196/ fix this problem? Or is that unlikely to fix this OOM, but still a Good Idea?
