APPCRASH StackHash_0a9e

[maximint]

Hi together,

I'm struggling since hours with crashing of my LabView Application on a W7 32bit maschine.
We use this application since years on WXP and since weeks on W7 maschines - without problems.

The executable is compiled on a W7 64 bit maschine (english lang.).
The problem occurs very often on a W7 32bit maschine (german lang.).
The problem seems to be triggerable by opening the windows explorer. But over night the crash comes without doing anything.

LabView Version is 2012 .0.1.f5 SP1  32bit

Does anybody has an idea?

Many Thanks, Thomas.

Hello Thomas! 

Would you mind attaching the actually crash log .txt file? 

[maximint]

Hi Nik,

attached the log files.

Thanks for help, Thomas.

Thomas,

Can you try running your executable on other Windows 7 machines and see if the executable crashes on these computers as well? 

[maximint]

Hi Nik,

same on other W7 machines.

Thx. Thomas.

[maximint]

I found the part in the program which seems to be the reason but ....

The suspicious program part is a simple select statement on a SAPDB database server.

Open DB, select, fetch, free, close DB.

If I delete this program part, the app does NOT crash.

If I enable it and make perform the select statement on a local MS Access database, the app does NOT crash.

Then I created a new exe only with the suspicious program part and a select on the SAB DB. And? The app does NOT crash.

Sorry, but I'm totally lost.

Does anybody has an idea?

Try to see if there is an updated driver for the db. It should be an ole type. Also, the db should be opened once at the beginning and closed when the program ends.

[maximint]

Hi,

the problem is solved.

Long time ago I was triggered by our DB administrator to close the server DB immediately after SQL statement,

and open it again if any other SQL action is necessary. But that seems to be the reason for the crash.

So, the server SAP DB will be opened after app start and closed when the app closes.

Many thanks for this tipp, Thomas.
