I have a scenario
JMS 1 -> XI (BPM 1) -> SAP R3 -> XI (BPM 2) -> JMS 2 (all interfaces are synchronous)
I found when BPM 2 is triggered, it doesn't work until timeout (PL_TIMEOUT). But if I only run SAP R3 -> XI (BPM 2) -> JMS 2, then it's ok.
The connection of RFC is 5, and I also test 2 paralle SAP R3 -> XI (BPM 2) -> JMS 2, it's ok too.
Is there any suggestion for me? I have no idea how to find the reason.
