I'm currently using several advantech devices with LabView, When I use one function with the dll it use memory, if I call it several time the memory used increased over and over ... to finally crash labview or have a bluescreen.

I've tried to flush the memory each time, it works better (crash after 30 min, before it was 10 sec ...)

  • You didn't give enough details to get an answer. If it is your code, please provide it. If not, this is probably not the right place to ask. – Lorenz Meyer Apr 18 '14 at 19:13
  • It's just the use of the DAQNavi advantech VI which produce the problem, I've isolated the problem. I was wondering if there was an existing solution to avoid crash from the dll ... Thanks – Mathieu Guarino Apr 18 '14 at 19:22
  • Could you add a snippet of your code? – Ton Plomp Apr 19 '14 at 03:58

  • image link : http://hpics.li/e502ee1 this is inside the section called by the hardware (or the simulation) I get an error at the "Control Set Config" which is just a dll Call ... – Mathieu Guarino Apr 19 '14 at 07:31
  • here is the snippet : http://hpics.li/25fa218 just the Advantech VI, configured for 4716 device with crash or in simulation : no crash – Mathieu Guarino Apr 19 '14 at 07:34

Problem solved after a few weeks :

There was a software memory leak in the manufacturer DLL. Changed my way of measuring to avoid the problem. There was only a few % of people having this problem
