labview program crashes every 64 days when running 24/7. Does anyone know why?

When I am running a labview program that monitors data 24/7, the program crashes every 64 days.  I am not trying to log any data using the program.  Does anyone know why it does this?

Hi

There is for sure nobody around who "knows" it. In addition to that, you have to provide more information. Have you been able to track the error to a special vi? Is there a special function in progress when the program crashes?

Give as much information as you can - otherwise it's really difficult to help you on this.

I can't argue with Thomas...

Guessing;

How often doe sthe tick count roll over?

What is happening with the memory usage over 64 days of use?

How many time have you seen it crash at this 64 day interval?

Posting your code may help us guess better.

I met the similar situation before. Mostly, it was caused by memory leaking problem.

Also, if you have network communication program, double check it.

49 days and the calculations should work OK with the rollover, so I don't think that's it.

The problem is not with a specific VI.  The whole labview program disappears after 64 days.  This has happened three times now, each 64 days appart.  When I come in the computer is working fine, but the labview program is no longer opened.  I have to open labview and restart the VI.  How do I monitor the memory usage over time?
