Hi Elvis,
We're having a similar problem with one of our cloud setups.
I'm currently running Solr 4.10.4 with 2 shards and no replicas. One of our
shards also keeps dropping off with the same error message. This happens
because the shard executes too many full GCs which completely freezes the
machine and causes zookeeper to think that it has dropped off. So I would
suggest that you analyze your gc logs and see if you're facing a similar
problem.
Moreover, I'm currently running the zookeeper that is embedded with solr.
Are you doing the same or do you have an external instance/ensemble setup?
So far, I've got no solutions but I'll update this thread if I find
anything.
