> Hi Team,
> I am using Apache geode as our distributed caching solution which internally using JGroups 3.6.10.Final version.
> I see this exception almost daily 5-6 times but we don't know the root cause for that. I tried reaching with Apache Geode community as well. As per their suggestion, it could be due to empty datagrams being sent to process. 
> I confirm that both of my client and server processes are using same version as 3.6.10.Final.
> I would request you to look into the same.
