Hi Lee
Hi Juhani
Can you tell more on how the regions are balanced?
Are you overloading only specific region server alone?

Hi
HBASE-5225 was merged for different purpose. But this issue does not seem
to be because of HBASE-5225.
Because in HBASE-5225 we tried to fix the case where the seq id is missed.
Here it is not missed it is still there in lastSeqWritten without getting
flushed.
