system halt after my program run

[China 23]

infoI make a program by LabVIEW 6i. The program function is that firstly it get data from OPC server by network, secondly to send command by RS-232. But the program do not run correctly. some information as follows:

1. computer: advantech industrial PC, CPU: P3-800(intel), memory:128M, HD:20G, display memory:4M(ATI), net crad: 3Com(3c905,10-100M)

2. system: windows NT4.0 workstation with SP4 (chinese), LabVIEW 6i

3. OPC: server: citect.opc (citect is automation & industrial software),
client: labVIEW.opc

4. some phenomena: when the program run after 4-5 hours or 10-12 hours, system halt and show that visual memory is shortage(visual memory of system is 160M).


I do not know why it is, need you help.

thanks
in advance.

Can't open your attachment because it's not a VI but I would look at array construction and references always being created and never closed. Good luck.

Dennis,

He's zipped it up. Unzip it, and you'll get a .llb. Open the .llb, and open the main.vi.

Two suggestion you might try:

1. Update your video monitor to the latest version.

2. Put a small delay (around 10 to 100 ms) in all your For and While Loops (including sub VIs). To create a delay, use the the 'Wait' sub VI in the Time & Dialog sub palette. This will force LabVIEW to pause momentarily and let Windows do other stuff....
