------------------------------------------

             Summary: Undroppable messages can be dropped if message queue gets large
                 Key: CASSANDRA-10113
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10113
             Project: Cassandra
          Issue Type: Bug
            Reporter: Yuki Morishita
            Assignee: Yuki Morishita
            Priority: Minor


When outgoing messages are queued, OutboundTcpConnection checks the size of backlog, and [if it gets more than 1024, it drops expired messages silently from the backlog|https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/net/OutboundTcpConnection.java#L150].

{{expireMessages()}} just checks message's timeout, which can be {{request_timeout_in_ms}} (10 sec default) for non- read/write message, and does not check if its droppable.
