This is great. NB: It may have been c/62674 or anything else that went in recently (anywhere incl. Bug 9028, dunno if that could have helped for this?) which did the trick, but it works now, so great! FYI this has been verified by both "wow, now it didn't blew up anymore with OOM" as well as confirmed via HPROF analysis through MAT (which now also revealed new Bug 9114; but that's another story). I'll therefore close blocker Bug 9034 as soon as you've agreed a final version of c/62674 and merged it (into carbon, nitrogen and master). The FYI: c/62674/5 does fix https://bugs.opendaylight.org/show_bug.cgi?id=9070, so I'll also close that after you merge. The Bad: The https://bugs.opendaylight.org/show_bug.cgi?id=9038 "IllegalStateException: Attempted to close chain with outstanding transaction PingPongTransaction" still appears in logs - sorry. So c/62674/5 *DOES NOT* fix blocker Bug 9038. You can also find related information on the new attachment on umbrella https://bugs.opendaylight.org/show_bug.cgi?id=9096 re. other Tx leaks. I'm hoping this information is useful to openflowplug-dev to find another solution for Bug 9038. Tx, M.
