Hi,

I am using single node JBoss 4.0.4 GA installation with Sonic MQ 6.x. The application sends JMS messages at a high rate using container managed transactions.

I see these errors in the log intermittently. On debugging further, it appears that the transaction is being registered with the ResourceManager (Sonic) twice in these case which leads to the enlist() failing.

I was wondering if anyone has seen a similar exception and fixed the problem.

Thanks in advance.
