Jonathan Graham created AMQ-4996:
------------------------------------
Summary: org.apache.activemq.transport.RequestTimedOutIOException
thrown by producer.send() for no obvious reason. Message is actually sent.
Key: AMQ-4996
URL: https://issues.apache.org/jira/browse/AMQ-4996
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Affects Versions: 5.5.1
Reporter: Jonathan Graham
In production we are getting
org.apache.activemq.transport.RequestTimedOutIOException exceptions thrown
sometimes when we execute the send command. The timeout is set to 5 seconds and
it blocks for 5 seconds and then throws the exception. The message is actually
sent to the broker successfully (I don't know if it's sent immediately or if
there was a delay before it gets there).
We are communicating with the broker via TCP but it is on the localhost.
This happens 'every so often' with no explanation that I can find. No errors
appear in the broker logs (and no clues when configured to DEBUG level). The
volume is very low; a message every 20-30 seconds or so, and they are
immediately handled by a consumer - the broker has not run out of storage or
memory.
It seems to happen in bursts (e.g. it happened 4 times within 10 minutes, but
not on every message, and then didn't happen again all day).
