> We had reports of this exception when using TLS for cluster communications. I wrote a test that set socket-lease-time to 1 second and then looped creating a thread to do a single 20mb put() and then waiting 2 seconds after the put() completed so that connections would time out.
> I saw message-length growth without the fix for GEODE-8506 that went away with the fix for that ticket. If I let the test go on long enough the message-length grew to over 16mb and the test failed with this error:

> While the fix for GEODE-8506 made it unlikely that we'll run into this again I think we should bullet-proof the MsgStreamer class to never try to send message chunks larger than Connection.MAX_MSG_SIZE.
> Note that we can still send cache operation messages larger than 16mb because MsgStreamer will break them into smaller chunks.
