niDMM Read Multi Point.vi times out - niDMM Abort.vi hangs

Hi all,

I've got a weird problem.
In my app there are multiple calls to two NI-PXI4070 DMMS to acquire multipoint measurements (some 50 calls per run and between 500 to 15k points per measurement). Sometimes during almost every run a call to 'niDMM Read Multi Point.vi' returns a timeout error, allthough I have set the timeout value to much more than what was required for the specific measurement. In order to handle this, I'v included a call to 'niDMM Abort.vi' whenever a timeout occured. But this calls hangs forever.

Trying to stop this vi opens a window stating '..resetting your vi..'. But it needs at least more than several hours to finish :-((. If I kill LV I get a BSOD claiming that there where locked pages. This indicates to me that the call to 'niDMM Read Multi Point.vi' was not aborted.

What can I do?

The german support request page seems not to work and Munich has a holiday today.

Greetings from Germany!
