labview shutdown without error message

[Anitram]

Occasionally when I run the attached VI it will shut down the entire Labview without leaving any error message. This seem to happen after about the same amount of time (around two hours) but once it makes it through that time it seems to be able to run forever (or atleast several days). I use Windows7 and since yesterday I have Labview2010SP1 instead of Labview2010. My programming skills are modest and when it comes to errorhandling and debugging I am lost. Especially when there is no error message. Has anyone experienced the same type of problem or knows any common reasons why Labview would shut down without even giving an error message please help me out.

Thank you

Hi Anitram,

probably some kind of ExpressVI-poisoning - or maybe the weird-wiring-syndrom?

Seriously:

ExpressVIs are good as starting point, but they may show problems when used for long-term measurements. Do your programming using "real" LabVIEW functions with proper data/memory handling and your occasional LV-crashes should go away...
