OOM and other memory issues

@Sam Hague lemme close this one (for Oxygen already, not Fluorine).

@JamO Luhrsen we need to get https://lf-opendaylight.atlassian.net/browse/NETVIRT-878#icft=NETVIRT-878 done soon-ish (waiting for @Stephen Kitt and @Anil Vishnoi in OPNFLWPLUG-982..). @Sam Hague FYI it's imaginable that https://lf-opendaylight.atlassian.net/browse/NETVIRT-878#icft=NETVIRT-878 lets us discover new OOM introduced since the last round, in netvirt or elsewhere, but let us deal with those, if any, in new issues; no reason to keep this one one.

@Michael Vorburger @JamO Luhrsen is there anything else for this issue?

@Sam Hague this issue is overly generic and not "actionable" for me. I'm "done" with all known OOM work as of now, Un-assigning this issue from myself so it does not clutter my TODO list; you can decide if / when you want to close it.

PS: The one remaining work item is https://lf-opendaylight.atlassian.net/browse/NETVIRT-878#icft=NETVIRT-878 , which I can "support" but not "drive" or "lead."

@Sam Hague this issue is overly generic and non-actionable. But have you seen the ongoing https://lf-opendaylight.atlassian.net/browse/NETVIRT-985#icft=NETVIRT-985 ? I'm inclined to close this one as a dupe of that one, would that be OK with you?
