How can i debug , find the problem????

The problem is using Counters in Cassandra 0.8.

But seriously, I don't know whether the particular issue you describe is fixed upstream. But if it isn't, no one will fix it in 0.8, so you should probably...

1) upgrade to Cassandra 1.2.9 (note that you likely need to pass through 1.0/1.1)
2) attempt to reproduce
3) if you can, file a JIRA and update this thread with a link to it
