-------------------------------------
Summary: Assert Errors occurring with OutboundTcpConnection causes
Cassandra to slowly stop functioning.
Key: CASSANDRA-12633
URL: https://issues.apache.org/jira/browse/CASSANDRA-12633
Project: Cassandra
Issue Type: Bug
Reporter: Jeff Beck
Assert Errors occurring with OutboundTcpConnection causes Cassandra to slowly
stop functioning.
There is a possibility of assert errors in ByteBufferUtil.writeWithShortLength
which can cause a stop to processing. There is already good error handling it
just needs to catch Throwable instead of Exception at
https://github.com/apache/cassandra/blob/c26bd91852cbf19d7dba9f62078f5da31b04dbe0/src/java/org/apache/cassandra/net/OutboundTcpConnection.java#L239
An example of when this happens:

{code}
The exact error happened when you sent a read request via cql for a clustering
column value with more than 64k chars much like CASSANDRA-8280 but on reads.
That exact error case is no longer reproducable in the latest versions of C*
but in general it seems like it should still handle the possible asserts.
