We are experiencing some random hangs while importing data into Cassandra 0.6.5. The client stack dump is below. We are using Java Pelops with Thrift r917130. The hang seems random, sometimes millions of records in, sometimes just a few thousand. It sort of smells like the JIRA
https://issues.apache.org/jira/browse/CASSANDRA-1175 Has any one else experienced this? Any advice?
