We are using ODL Nitrogen version. When we perform warm start (ie., restart Karaf servers, without deleting "KARAF_HOME/data" folder following bundles are in "GracePeriod" state for a long time, hence other application bundles that are dependent on this are failing. However when we start Karaf in a clean (without data folder) state, all bundles comes up fine.
We also noticed, netty.tcp port 2550 is not getting binded when bundles goes into failure state. Confirmed this port is not being used by other process also.

We also observe following logs rolling continuously and only this message is coming very frequently. It seems that its not allowing any other bundles to co-perform.

Please let us know
You need to set SO_REUSEADDR to enable the port to be directly reused after it is closed. See https://docs.oracle.com/javase/7/docs/api/java/net/StandardSocketOptions.html#SO_REUSEADDR If you do not set this option then the port will stay blocked for a while dependent on the operation system.
You should also not forcefully kill a process if possible as this does not cleanly shut down the ports.
