Hi Gurus,

One of our applications is crashing after migrating to PB2017R3 (running app using PB IDE or built).  It shuts down after 3 minutes either active or idle.  This application uses PFC, but migrating or not migrating the framework still results on the same behavior.  We currently have this thought that this issue is within the application code that is not compatible with PB2017, but it's difficult to figure out as of now.  I looked on an unresolved post for possible answers, but it seems to be not applicable to our issue.


Event log:

Faulting application name: PB170.EXE, version:, time stamp: 0x5b6318f9

Please advise, I can provide more details.  Thanks in advance.

Hi Jeff;

  The ntdll.dll is a DLL developed originally by Oracle and now adopted by MS-Windows as part of the O/S's exposing the WinAPI SDK calls to any application. The fact that it failed in there might indicate that your App was performing some sort of O/S external function call when it failed.

  Since your application was just idling at the time of failure ... does your App use various timers in the background? If so, do any of those fire events of functions that issue MS-Windows calls?

Regards ... Chris

Hmmm ... That's not a big PB run-time base code change. I am surprised at the stability issue. However, when I was upgrading my STD framework to PB 12.6 & PB2017, I did notice that had to "tweak" a few old MS-Windows SDK calls from ANSI to Unicode ("W" - wide) calls in order to make a few things work OK. So you might want to review your External Function declarations.

Also, check to see if you have any active Window "Timer" events or TIMING NVUO features in play. That also includes what your App might be doing on the IDLE event as well.

Hi Chris,

We have tried your recommendations and it didn't work. We narrowed down that this is an incompatibility issue, so I submitted a ticket.

Hi Jeff;

Looks like ticket #2023.

I see that Adrian from Appeon has responded to you on that ticket already for more information.
