Diadem 2018 and 2020 crashes with windows 10

[mrme]

Hi,

We changed from windows7 to windows10.  Now I (and at least one colleague) get frequent crashes of Diadem.  The same behaviour occurs for versions 2018 and 2020.  Diadem does not log an error.  In Windows event log I see an error referenced to "KernelBase.dll". 

The crash appears to occur after clicking on a channel in the Portal.  I am using just a small fraction of the RAM available....

Has anyone else met this - any ideas?

Thank you.

Hi Thomas,

Does DIAdem also crash during PDF export?

Hi Thomas,

I have tried to export to pdf and it works ok.  But the problem is intermittent - happens about 5 times a day.

It seems to crash following a pattern of events: -

(1) I click on a channel

(2) The cursor spins (as if slow)

(3) The cursor stops spinning for a moment

(4) The cursor spins a second time and then stops

(5) A moment later - Diadem crashes.

The windows event log shows three error events per crash, the first one is a  'The process was terminated due to an unhandled exception......', the other two point to KernelBase.dll...

Thanks for the help

Thomas

I assume it is not related to the operating system but to the fact that the characteristic values are calculated in the moment you click a channel if preview is open.

So the spin you see is this calculation.

I would assume the crash will show up during load of the file you enable the calculation of the values in the settings dialog.

But thats how older DIAdem versions worked. Calculate it on load.

So there are two things you can try

• Close the preview window if you do not need it
• Calculate the characteristics on load of files

---

• Could you give a hint which file format/Dataplugin you are using?
• Could you reproduce it by opening the same file afterwards and click the same channel?
  If yes, could you share one of the files.
• Are those files large? Which number of values do those channels contain?

Hi Andreas,

Thanks for the response.  Since two days, the problem has not appeared...

Typical file info:-

• TDMS (previously created by a Diadem script from multiple text files)
• 1 GB size.
• 6600 channels.
• Numeric and time channels containing 8800 values.
• Text channels containing 8800 values.
• About 12% of the channels are text.

Other info

• Unfortunately, I cannot share a file (customer data).
• Cannot reproduce the problem at the moment.
• Similar files were processed with Diadem 2018 and Win 7 for one year without problems.  The problem first appeared after switching to Win 10.
• The problem is not consistent - occurs sometimes only.
• The files load ok.
• I set characteristic values to calculate automatically on load - works ok, no crash (yet).
• A colleague with a similar problem did an update (NI) and it has been ok since.
• I didn't do an update and it is also ok since two days.

Thanks again

Thomas
