Symptoms

 On JBoss side : 

2 distinct transactions TRANS-A and TRANS-B launched at the same time from JBoss application server. The 2 transactions are propagated to Tuxedo when calling service SVC through JCA. There are several Tuxedo server instances publishing the same SVC service. 

• The first transaction TRANS-A is propagated : on Tuxedo side, the service SVC is performed by server SRV-1 using Tuxedo GTRID-1

The transaction will succeed.

• A second transaction matching with the second transaction (on JBoss side reference being TRANS-B) is  launched on Tuxedo side. On Tuxedo side, the service SVC is performed by server SRV-2 using Tuxedo GTRID-1

The transaction can't commit.
