If no reply is received (e.g. because of message loss or because the CLM server
died before being able to reply), then the CLM node agent is stuck in the
blocking send until it times out. No election can happen on this node, and it
cannot send a new join request either in case a new CLM server appears.

** [tickets:#2220] clm: Main thread of node agent is blocked due to synchronous
message sending**
**Status:** accepted
**Milestone:** 5.0.2
**Created:** Thu Dec 08, 2016 02:30 PM UTC by Anders Widell
**Last Updated:** Fri Dec 09, 2016 09:18 AM UTC
**Owner:** Anders Widell
The CLM node agent performs a synchronous send with a long time-out towards the
CLM server. If there is no response from the CLM server, this could cause the
main thread in the CLM node agent to be blocked for a long time.
