Error description

  • Deadlocks may occur if end of process-scoped event handler and
    last activity of process execute concurrently
    .
    If the last activity of a process-wide event handler and the
    last activity of the process execute concurrently,
    deadlocks may occur. This is due to the fact that these 2
    actions happen in distict threads that compete for resources,
    especially the process instance and its associated top level
    scope.
    .
    This fix solves the problem by requesting an exclusive on the
    process instance when the end of an event handler is processed.
