Shunning and the exception sound like two symptoms of the same problem -- a machine that's overtaxed.  Preventing shunning doesn't solve the underlying problem.

Your FD protocol has a very short timeout/max_tries combination.  With that, a busy machine that takes a while to respond to a heartbeat (perhaps just due to a long garbage collection) will get suspected.  The default recommendation for FD now is timeout="10000" max_tries="5".

What's your SyncReplTimeout setting?  Bumping it up will help prevent the exception.
