http and bpm

Hello,

I have a scenario: HTTP -> XI (BPM).

The Integration process:

1. Receive (Opens S/A Bridge)

2. Send (Closes S/A Bridge)

Error:

INTERNAL.PL_TIMEOUT

Timeout condition of pipeline reached

The Integration process has not started. When I send message with qos=EO the integration process has started.

I have not any mappings in my scenario.

anyone has an idea?

Thanks
