lost transactions ???

Hi all,

We have problem with BPEL processes on Weblogic 10.3.5.

Sometimes BPEL process after returning from asynchronous process invocations somehow loses transaction or smth. and do not commit last changes:

BPEL0 read from AQ and invokes EVENT1.

BPEL1 starts from EVENT1:

- DB invocation1

- DB invocation2

- Async call process BPEL2

  - DB invocation3

- Async call process BPEL3

  - DB invocation4

<--- here something happens, and all next DB invocations results are lost.

- DB invocation5

- DB invocation5

Sometimes (after connection pool restart) 1 or 2 times everything works correctly. But only few times.

All times FLOW TRACE shows no errors, no rollback, everything seems ok. BPEL processes states completed.
