Subject [jira] [Commented] (AMQ-1870) JDBC exception when sending and receiving a lot of messages (MySQL 5 in use for persistence)
Date Tue, 09 Oct 2012 13:00:08 GMT

    [ https://issues.apache.org/jira/browse/AMQ-1870?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13472330#comment-13472330

PJ Fanning commented on AMQ-1870:
---------------------------------

Hi Gary, Claus,
I raised this issue in 2008 and I don't really use ActiveMQ much these days.
I have never modified the ActiveMQ default config, other than to set some environmental settings
(eg the MySQL connection details).
Thanks for looking at the issue though.
For the prefetch logic, it does seem sensible to limit the rows to the 100s as opposed to
1000s.
Sorry I can't be of much assistance.

> The number of messages that were on the queue was approx 3 million when this exception
happened. Would it be possible to modify the code so that the setMaxRows value is kept to
a much lower number?
