Subject [jira] [Commented] (AMQ-4335) Cannot set maxFrameSize greater than 100MB
Date Mon, 25 Feb 2013 14:52:16 GMT


Lucille Wilson commented on AMQ-4335:

I set the maxFrameSize in ACTIVEMQ_HOME/conf/activemq.xml to 1 mb.
Then I created a junit test class which created a 2 mb message.  I expect that if my setting
of maxframesize is respected the message will produce an error saying frame size of 2mb is
larger than the max allowed of 1mb.

However, the message was enqueued. 

Please see

I believe I have proven that Activemq has hard-coded a 100mb limit in the maxframesize and
that any overrides set are ignored.  We'd like Activemq to fix this bug, please.  Please let
us know when the bug is fixed and where to download the software.
