Description
Following the (many!) fixes that we did in NETVIRT-985, a new round of testing on the latest stable/carbon using the "nova-boot scenario" has hit an OOM again. A new "trace:transaction" output reveals more TX leaks which we need to plug; see attached.
The biggest one with 273x open newReadOnlyTransaction likely causing the new OOM this time appears in (1) ovsdb; https://git.opendaylight.org/gerrit/#/c/65567/ seems to not have helped for that one - curious... or we made a mess in downstream porting?!
Filing this in JIRA project ovsdb due to above; but the attached shows a number of other leaks in (2) openflowplugin and (3) genius.lockmanager & (4) genius.interfacemanager (x90!) which we need to plug as part of this JIRA as well.
