[jboss-user] [EJB 3.0] - Deployment of node 2 fails in JBoss 4.0.5.GA + EJB3 RC9 patc

[J.Hedin]

We use JBoss 4.0.5.GA + EJB3 RC9 Patch 1+ jBPM 3.1.3 with store in MySQL 5 for our application. The application runs in an active-active cluster on two nodes. The flow is mainly

MDB (starts TX) -> token.signal() -> jBPM actions (often calls EJB3 SLSB -> EJB3 entity beans) -> JMS send tokenId to queue

and

EJB3-timer (starts TX) -> jBPM timers -> jBPM actions (SLSB -> Entity beans) -> JMS send tokenId to queue

We had problems with lockup with previous version of JBoss AS/EJB3, but all is stable now. http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008021#4008021
Thanks all for great help.

We can however not add a second node under a heavy loaded cluster. By turning on some log4j debugging, the load on the cache is reduced enough to make the second node start. The application uses opportunistic locks. The test data generating the load is a worse case scenario with loads of lock errors and roll backs. Also the MDB sleeps 5s +- a small random time on lock error.
