[BGPCEP-113] bgppcep: connection odl/cto <---> exabgp tool not stable

Sun, 3 Mar 2019 11:50:16 +0000

odl details:
org.opendaylight.controller.version = 0.1
org.opendaylight.controller.build.scm.version = 34bd6d37787f85ec228bd0dc5c1ff399ebd649b1
org.opendaylight.controller.build.user = jenkins-controller
org.opendaylight.controller.build.workspace = **********
org.opendaylight.controller.build.timestamp = 1406126629215
org.opendaylight.controller.build.machine = **********

A while after the bgp connection is established and updates are sent, odl initiates new session. I suspect that the following ex exceptions may cause it.

2014-07-24 00:51:44.631 PDT [nettyThreadgroupModule$NioEventLoopGroupCloseable-7-1] WARN i.n.channel.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.
