Hbase FATAL error

I been getting these errors from time to time seams like
when the region 
servers are under a load for long time they start failing
with this error. 
nit all at the same time but it happens on different
servers. I know this is 
not an network problem as one of the region servers is on
the same node as 
the master.

org.apache.hadoop.hbase.HRegionServer: unable 
to report to master for 33730 milliseconds - aborting

regionservers will shut themselves down if they are unable
to contact 
the master.  Can you figure what the master was doing such
that it 
became non-responsive during this time?

HADOOP-2343 describes regionservers 'hanging' inexplicably. 
Do you 
think you are experiencing a similar phenomenon?
