Null pointer exception

Hi,
      My hbase suddenly goes down,

when i check the logs, i get the following exception at master node's region
server:

2009-04-15 08:37:09,158 FATAL
org.apache.hadoop.hbase.regionserver.HRegionServer: Unhandled exception.
Aborting...

Hi Rakhi,

I filed a bug report for this as HBASE-1327:
  https://issues.apache.org/jira/browse/HBASE-1327

Please advise if I have any of the details on the issue
incorrect.
