    Hi,

    I am using libACE-5.8.1.so version in my application. When i shutdown my application it crashes .
    Application is shutdown using kill command from bash script. In my application these are handled by using ACE_Event_Handler class.

    My application started below services using ACE library logger service, configure service, Monitor service.

    stack trace are given below

    After analysing the core i found that in definition of ACE_Event_Handler_Handle_Timeout_Upcall<ACE_LOCK>::deletion function dont_call value is 0 for function cancel_type and cancel_timer. But my application crashes at call of event_handler->handle_close
    inside cancel_type function.
    If i pass dont_call value 1 then there is no problem in application shutdown.

    Please suggest me is it proper fix or something incorrect in my application?
