Hi,
For the next OPNFV release (Colorado), we are trying to test SFC with ODL Boron
but we are hitting some problems. One of them appears in around 50% of the
deployments and seems as if the problem is in the openflow plugin. We see the
following in the logs of OVS:
2016-07-25T15:36:37.180Z|00104|rconn|INFO|br-int<->tcp:192.168.0.44:6653:
connected
2016-07-25T15:36:37.183Z|00105|rconn|INFO|br-int<->tcp:192.168.0.44:6653:
connection closed by peer
And at the same time, we see the following in ODL logs:
2016-07-25 15:36:29,178 | INFO | ntLoopGroup-11-7 | ConnectionAdapterImpl

That results in the switch not getting any flow. Restarting ODL solves the
problem partially: we don't see those connection problems anymore but then we
only get a few flows and not all of them.
Have you seen this problem? Did you perhaps already found a solution? We are
working with a ODL build which is around 2 weeks old and perhaps this was
solved already.
Thanks,
Manuel
