A new "trace:transaction" output reveals more TX leaks which we need to plug; see attached.</p> <p>The biggest one with 273x open newReadOnlyTransaction likely causing the new OOM this time appears in (1) ovsdb; <a href="https://git.opendaylight.org/gerrit/#/c/65567/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/65567/</a> seems to not have helped for that one - curious... or we made a mess in downstream porting?!</p> <p>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 &amp; (4) genius.interfacemanager (x90!) which we need to plug as part of this JIRA as well.</p> OVSDB-435
