real time image processing: RT crashes intermittently

Re: real time image processing: RT crashes intermittently

Hi Wei,

 

The other forum post you referenced is discussing a crash in RT, but the two look completely unrelated. The other crash is something inside of LabVIEW in a LabVIEW thread that is crashing.

 

In your crash it appears to be something related to shared variables. Since the support in the shared variable engine for images is brand new, I am suspecting there might be something related to the image transfer over shared variables. Could you try running it with the string datatype and the flatten/unflatten on either end so we can confirm if this is the case? This will allow us to properly assign the bug to the correct group to investigate.

 

Thanks,

Eric

Hi, Eric,

 

Really thank you for your timely response.

 

Actually when you look at the attached error log you will find out there are two errors. One is labview error associated with PH_EXEC_SMP and each time I restart the RT PC, this error is logged but this error never crashes the RT PC-- Remote PC system.   The other error as you can see is the crash error log. And this error is the one crashes the system each time and this error, in my understanding, is the RT crash error and it is exactly the same error experienced by the other guy Tavi before image shared variable is released.  So this is why I think the image shared variable is not the reason for RT crash. 

 

But I will try what you suggested about the string, flatten/unflatten.  Do you have any example on that?

 

Regards,

 

Wei

Hi, Eric,

 

I did a close look at Tavi's error log and mine, you will notice they are almost the same.

 

Tavi's error log:

My error log expecially at the begining part is the same as Tavi's, so do you have any thoughts on that?

Hi, Eric,

 

I tried to flatten/unflatten the image to string and transfer the images through this way. Great news is that so far it works without crash.  I don't know if this finally works out since I still need to take some time to test the stability of the system.

 

Thank you very much for your great suggestions and help.

 

Regards,

 

Wei
