Lv crashes every 10 days, "plotsupp.cpp, line 1330"

[millerg]

This vi continually writes to a buffer and displays on a waveform chart. Upon a trigger signal, a predefined amount of data (in the buffer) is written to a file and the vi ends. Labview is crashing every 10 days with failure message "plotsupp.cpp, line 1330". Mac G-4, OS 9, LabVIEW 6.1, 6031 I/O Card, 38 channels of data.

Hello �

What happens every 10 days? Does the program get to the same specific point after 10 days of running? What does that specific part of the program do? Does the user have interaction with the VI or is it running by itself?

The only report of this error crash we have is when the user tried to modify the labels in a control. Somehow the control got corrupted and the problem was fixed by replacing the controls in the front panel with new ones.

If this does not help, you can narrow the problem down and post a simple VI so that we can reproduce the issue.

Reports of this machine crashing were passed to me to look into since I wrote the LabVIEW program that it is running. The vi does an AIConfig-AIStart-AIRead. AI Read is in a loop which writes to a Waveform Chart. If a trigger signal is sensed on Ch0, the loop ends and AI Read (Buffered) sends a predetermined chunk of the buffer to a file. Once started, the vi runs continually, with no user interaction, until a trigger signal occurs, which may be never. I will try to get more info after the "next crash".
