Subject zkState changes too often
Date Tue, 16 Apr 2013 16:49:39 GMT
Hi

I am using SolrCloud (4.1) with 6 nodes.
When i index the documents from the mapper and as the load increases.. i see these messages
in my mapper logs…
WHich looks like it is slowing down my indexing speed.

I tried increasing the Zk timeout from 15 to 20 sec… but i still see this message…
anything i might try to avoid this?
