I deleted a column family from the keyspace and the error has gone now.

Thanks for the reply.

What was the node doing right before the ERROR? Can you post some more log?

Subject: java.lang.AssertionError on starting the node

    I have created a 2 node test cluster in Cassandra version 1.2.3 with  Simple Strategy and Replication Factor 2. The Java version is "1.6.0_27" The seed node is working fine but when I am starting the second node it is showing the following error:

ERROR 10:16:55,603 Exception in thread Thread[FlushWriter:2,5,main]
java.lang.AssertionError: 105565

This node was working fine earlier and is having the data also.
Any help would be appreciated.
