---------------------------------------
Summary: Multiple RPC threads waiting on a single thread
Key: CASSANDRA-4387
URL: https://issues.apache.org/jira/browse/CASSANDRA-4387
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.0.7
Environment: sun java 6.24
Reporter: Jason Harvey
Priority: Minor
Attachments: output.log
I'm investigating a load spike issue on our cluster. A thread dump that I
collected during a spike shows a peculiar symptom. There are 162 RPC threads
all parked waiting on a single
java.util.concurrent.SynchronousQueue$TransferStack thread. Brandon took a peek
and recommended I create a ticket for investigation.
Full thread dump attached. The thread which is being waited on is
0x00000006ac1aba60.
