Hi,
Since the 2012-09-17 11:10:41 build shards start to have trouble coming back
online. When i restart one node the slices on the other nodes are throwing
exceptions and cannot be queried. I'm not sure how to remedy the problem but
stopping a node or restarting it a few times seems to help it. The problem is
when i restart a node, and it happens, i must not restart another node because
that may trigger other slices becoming unavailable.
Here are some parts of the log:
