Sylvain Lebresne updated CASSANDRA-4219:
----------------------------------------
Attachment: 0001-Add-debug-logs.txt
Would that be possible for you to try applying the attached patch
(0001-Add-debug-logs.txt) on one of the machine, switch the log to DEBUG, try
recreating said keyspace and send us the resulting log. This should give us
more info on what's going on.
Also, do you still have the log of when you first got the 'TSocket read 0
bytes' during a select? Is there any corresponding errors?

> Hi,
> I'm doing testing and wanted to drop a keyspace (with a column family) to
> re-add it with a different strategy. So I ran in cqlsh:
> DROP KEYSPACE PlayLog;
> CREATE KEYSPACE PlayLog WITH strategy_class = 'SimpleStrategy'
> AND strategy_options:replication_factor = 2;
> And everything seemed to be fine. I ran some inserts, which also seemed to go
> fine, but then selecting them gave me:
> cqlsh:PlayLog> select count(*) from playlog;
> TSocket read 0 bytes
> I wasn't sure what was wrong, so I tried dropping and creating again, and now
> when I try to create I get:
> cqlsh> CREATE KEYSPACE PlayLog WITH strategy_class = 'SimpleStrategy'
> ... AND strategy_options:replication_factor = 2;
> TSocket read 0 bytes
> And the keyspace doesn't get created. In the log it shows:
> ERROR [Thrift:4] 2012-05-03 18:23:05,124 CustomTThreadPoolServer.java (line
> 204) Error occurred during processing of message.
