Subject AssertionError in hintedhandoff - 1.0.5
Date Mon, 05 Dec 2011 23:52:10 GMT
Hi,

 We are running a 8 node cassandra cluster running cassandra 1.0.5.
All our CF use leveled compaction.  We ran a test where we did a lot
of inserts for 3 days. After that we started to run tests where some
of the reads could ask for information that was inserted a while back.
 In this scenario we are seeing this assertion error in HintedHandoff.
 Is this a known issue?
