During user tests, the application object manager exposed crashes that first appeared to occur randomly. Later, a repeating crash pattern was revealed. Below is the corresponding call stack (from the call to the signal handler at stack frame #10 down to the Logoff() call which showed that the crash is triggered during a session logout).

Raising the log level to 5 for event type "ObjMgrSessionLog" can reveal object leaks during logoff. A leak of business service "Web Engine Interface" or "Web Engine HTTP TXN" can be another symptom of the issue:
ObjMgrSessionLog    Debug    5    (...)    Business Service leak: Web Engine Interface
No consistent steps were found for recreating the issue, because (a) when the object manager crashed, all its user sessions were taken down, so the test users were not able to determine whose session was the one that triggered the crash; and (b) the scenario does not always lead to a crash.
