I have set up elasticsearch 0.90.2 on 4 linux VMs (ny01, ny02, nj01, nj02).  
There are 4 shards and 3 replicas for each (each node should have all 4  
shards). There is one index (we'll call it my\_index). Settings that we have  
modified from the defaults:  
discovery.zen.ping.multicast.enabled: false  
discovery.zen.minimum\_master\_nodes: 3  
cluster.routing.allocation.awareness.attributes: datacenter

Today I noticed that nj01 had lost 2 shards and nj02 had lost 1 shard.  
Looking at the logs, I see that after some disconnects around 2013-08-04  
07:00, ny01 tried to send the cluster state to all nodes. It looks like the  
correct cluster state was never fully recovered and these 3 shards remain  
unassigned. This is the logging from nj01 starting at that time.

Any suggestions how to debug why the full state was not recovered?

I have pasted the logs during that time from one of the problematic nodes  
(nj01) and from the master node at the time (ny01):  
ny01: [https://gist.github.com/takism1/312e2bf2d0ff583a235f](https://gist.github.com/takism1/312e2bf2d0ff583a235f)  
nj01: [https://gist.github.com/takism1/0162dda53b4806d7a372](https://gist.github.com/takism1/0162dda53b4806d7a372)

I can post additional information if needed.

Thanks,  
Takis
