Zookeeper ConnectionLossException

Hi All,

What would be the reason for getting this exception while running a
topology? Everything works fine for a while, and then I get this error and
the topology dies.

 org.apache.zookeeper.KeeperException$ConnectionLossException:
KeeperErrorCode = ConnectionLoss for /storm/partition_6
...
...
[main-SendThread(localhost:2181)] INFO

thank you
