Subject [jira] [Commented] (APLO-1) "Detected store dropped message" errors when broker is run against the stomp-benchmark
Date Wed, 01 Jun 2011 23:20:47 GMT

    [ https://issues.apache.org/jira/browse/APLO-1?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13042507#comment-13042507
] 

Hiram Chirino commented on APLO-1:
----------------------------------

I've updated the BDB store so that if it gives failed message load attempts a 2nd try just
in case there's a timing window bug.  I've also added better error detection and retry logic
so that if BDB does run into an odd situation like out of file handles or something, that
it will keep retrying the transaction until it succeeds or the broker gets shutdown.  Also
added a bit more logging if that case is encountered.
