U12 with LJlogger runs for roughly 36 hours then program freezes

Howdy we have been having troubles with a chamber locking up on us.  Not trusting how it handles the temp when this happens we wanted to monitor it seperately, we had a U12 Labjack on hand with EI-1022.  After familiarizing myself with it, installed latest tools from website (got them last week) on spare PC configured it up and started logging. 

2 attempts now; first time about 36 hours in, second attempt about 40 hours in LJlogger reports in windows it is not responsive and I have to close the program and restart.  As expected with program dead U12 stops working.

My setup is very simple:

1- EI-1022 setup for differential is using lines 0 and 1, then 2 I use to calc C and 3 I calc F.

2- Only other thing going on is in Triggers I setup a heartbeat on the U12 LED to monitor it easier.  Rather simple trigger runs for 2 seconds turns off LED for 0.5 seconds.  Its blinking its working basically.

At the very least I need this to run over a weekend.  Any ideas on what could be killing the program, guessing memory leak of some sort.

 

Thanks for any help.

Have not heard of anything

Have not heard of anything similar.  Please send/post a screenshot of the main screen and configure screen so we can set up the same and run it here.

What is the minimum you have to do to get going again?

I have to force close the program and restart.  That mostly does it the LED heartbeat seems to start up totally off have to edit Trigger to get it going again.

See pictures of setup and included PC details, Logger tells me op sys is Vista when PC is Win 7 Prof.

Let me know if you need anything else.  Really like to get this working right, a couple of these (well the T7 Pro version) would come in handy, but no one will buy anything if keeps crashing.
