Description

I am seeing frequent timeout errors when doing programmatic traces via trace_next_query()

ERROR [TracingStage:1] 2013-06-18 19:10:20,669 CassandraDaemon.java (line 196) Exception in thread Thread[TracingStage:1,5,main]

Attached is the sample code which produced this error and the logs. The error occurs directly after the INSERT statement.
