[jira] [Commented] (CASSANDRA-4573) HSHA doesn't handle large
messages gracefully
[ https://issues.apache.org/jira/browse/CASSANDRA-4573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13454602#comment-13454602 ]

----------------------------------
Hi Tyler, I am not able to re-produce it so far. I am running 2GB/400MB on AWS M4XL....
[ec2-user@ip-10-82-21-221 ~]$ grep -i ThriftServer.java /mnt/log/cassandra/system.log

The Timeout happens both in Sync and HSHA servers (randomly and i am not able to reproduce both cases reliably) and the only thing which i can notice is that the client (pycassa) runs 100% CPU most of the time... other than that everything else looks normal.

> HSHA doesn't seem to enforce any kind of max message length, and when messages are too large, it doesn't fail gracefully.
> With debug logs enabled, you'll see this:
> {{DEBUG 13:13:31,805 Unexpected state 16}}
> Which seems to mean that there's a SelectionKey that's valid, but isn't ready for reading, writing, or accepting.
> Client-side, you'll get this thrift error (while trying to read a frame as part of {{recv_batch_mutate}}):
> {{TTransportException: TSocket read 0 bytes}}
