External issue ID: 5769

 Description   

after briefly running some upstream CSIT system test suites in a local environment, it's noticed that we cannot make a basic ovsdb connection
from ovs node to controller (e.g. "ovs-vsctl set-manager")

with TRACE level debugging on org.opendaylight.org.lib these are the
only logs we see when ovs tries to connect:

2016-04-20 23:59:03,767 | INFO | entLoopGroup-4-1 | LoggingHandler | 127 - io.netty.common - 4.0.36.Final | [id: 0x57ee0ca6, L:/0:0:0:0:0:0:0:0:6640] RECEIVED: [id: 0xd237f166, L:/172.18.182.15:6640 - R:/172.18.182.7:49829]

attached is the karaf.log which will have logs that came while things were
ok and system tests were passing. Also attached are two packet captures
showing traces when this problem is happening, as well as when things are
ok (just for reference)

these are the logs after recreating from scratch.

1 start karaf
2 load odl-ovsdb-southbound-impl-rest
3 enable TRACE debugs on org.opendaylight.ovsdb.lib
4 manually connect ovs and verify it's in operational
5 run robot suites
6 manually try to connect ovs (this does not work)

after step 4 you will find a log message:

"JAMO JUST CONNECTED AND DISCONNECTED NODE. NOW RUNNING ROBOT SUITES"

after step 5 you find this message:

"JAMO JUST SAW ROBOT SUITES FINISH"
