We have set up solr 4.3 with master/setup and are facing a couple of issues,
Index locking, the index on slave hangs at time and when we restart the core
the core get's locked up. I have checked the logs and there are no OOM error or
anything else other than the error given below,Caused by:

and also replication stops. This was not happening with our earlier setup of
solr3.6
