Subject [jira] Resolved: (AMQ-2065) Inactivity monitor fires on slow transfer of large message
Date Mon, 02 Feb 2009 13:49:59 GMT


Vedran Vrbanc resolved AMQ-2065.

    Resolution: Duplicate

This is a known issue. It is caused by a bug in the InactivityMonitor transport class.

The cause and workaround is explained in more detail in AMQ-2088.

> I have been investigating using ActiveMQ as a transport for shipping PostgreSQL log files
as a method of offsite backup.  PostgreSQL periodically produces 16meg files which I package
up in a BytesMessage and place on a queue which is then emptied by an offsite machine.  This
works fine when testing locally over fast links, but when trying it over slow links the inactivity
monitor throws an exception part way through the message transfer despite a network dump showing
constant data traffic.
> I am guessing this is because the monitor does not recognise the transfer of the data
as activity, only the command to retrieve it?
