Hi everyone,
I'm experiencing a rather annoying (and increasingly frequent) problem....
I have a program using several different modules for instrument communication (Spectrometer, filter wheel, monochromator etc) which has been running fine for a year or so.
Recently, I have problems with LV bombing out in the middle of a measurement. No error messages from LV, a system-level crash. I'm not used to this kind of thing.
Following pictures are details of ONE type of crash (it has two or three different "forms").
The dialogs appear in this order:



Details on my system:
- I'm using a dell (I've seen reports of problems regarding this before....), but the crashes happened on an old no-name beige box before also.
- The VIs are saved with diagram on a network drive (Both PCs using WinXP Pro with up-to-date patches).
- I am calling a DLL for a spectrometer interface, but testing this code on its own for several hours cannot generate a crash.
- All other functions are built-in G.
- It seems kind of fond of crashing in the middle os a gauss-fitting routine I've written (Heavily modified Levenberg routine). This code has also worked without any problems since over a year.
- I am using 3 RS-232 ports (Filter wheel, Spectrometer, Linear stage) and 2 USB ports (Spectrometer via DLL, Relay via Command-line parameters).
- The crashes seem random with no single module causing the problems (except for the affinity mentioned above). Sometimes I can even finish a complete measurement series (oooh) whereas sometimes I only get through 10 or 30 or 50%.
I'm at a loss currently. I've looked at as much of the code as I can, and I can't see anything wrong. I've even tried copying the code to new VIs, but this hasn't stopped the crashes.
Please help....
Shane.
