During high load you see stuck threads in your OSB domain.
The threads are receiving a message and are waiting for the outbound sendAsync() operation to be completed before processing it.
They are trying to acquire a semaphore but the thread which acquired (and should have released) the semaphore is not available any more.
The majority of the execute threads have the following stack trace:
