    PIACEClassLibraryHost.exe periodically crashes


      Hello, everybody!


      We have several executables that are hosting on one ACE Scheduler.


      Every executable is running as a separate process called PIACEClassLibraryHost.exe.


      One executable periodically crashes one time in several days with the following record in Windows EventLog

      Faulting application name: PIACEClassLibraryHost.exe, version:, time stamp: 0x4e02943a
      Faulting module name: unknown, version:, time stamp: 0x00000000
      Exception code: 0xc0000005
      Fault offset: 0xff006a04
      Faulting process id: 0x1bb8
      Faulting application start time: 0x01cec36f4f4f04f8
      Faulting application path: C:\Program Files   (x86)\PIPC\ACE\Scheduler\x86\PIACEClassLibraryHost.exe
      Faulting module path: unknown
      Report Id: 5c7dc01a-2fb1-11e3-bff8-005056b2032d

      All calculations hosted on this ececutable stop while other ececutables resume there calculations.


      It should be mentioned that "failed" executable calculates very well between crashes.


      We have to manually restart PI ACE Scheduler to restore normal work but other executables interrupt there work between restarts.




      Thus, we have several questions about this:

      1. What are the reasons of such type crashing and how to prevent it?
      2. What should we do to restore the work of "failed" executable without restarting PI ACE Scheduler?
      3. Are there any ways to exclude human participation in elimination of crash consequences?



      Thank You for replies!
