==Proposed Release Note==

Issue with MySQL / Linux / JBPM

In testing concurrent signalling from multiple threads has been detected running JBPM on Linux using MySQL as the database. As such this combination is currently *not recommended* for production use.

(Do we say *not supported*?)



Comment 8 Mark Little 2008-01-17 21:20:04 UTC
According to http://jira.jboss.com/jira/browse/JBPM-1072 the problem may even be specific to certain versions of MySQL. Best talk with Len to get combination that failed and document those specifically. Then I'd say Not Recommended, because many areas of jBPM do work.

6.2. Issue with MySQL / Linux / JBPM combination

When JBPM is deployed on Linux using MySQL version 5.0.45 as the database concurrent signalling from multiple threads has been detected. As such, this combination is currently not recommended for production use. This issue is not present with MySQL version 5.0.27.

Further Information: SOA-196
