LabView causes system to lock up when editing block diagram of large application

[SV-George]

I am attempting to go through a large application which was written for on a different machine with I/O attached. I am looking at it on a plain PC with no attached hardware. The application loads, I can get into the block diagram, but after viewing it for just a short time the display freezes (including the taskmanager), then the keyboard locks up. The only way out is to cycle the power on the PC. This is running W2K on a 550Mhz pentium III processor with 256MB RAM and a new installation of Win2K with all updates applied. This is with LabView 7.1. I can run smaller subvi's with no problem.

I am new at LabView, so any help is appreciated.

Hi George

what kind of Hardware - IO do you use in the app? are there any DAQ-channel- or VISA-Connection-constants in your diagramm? maybe the problem is not the size of your code but the missing hardware...

best regards

Chris - since this fails while editing the block diagram, not while running the code, I assume that the drivers would not be active. Also, ideally an application should not be able to crash the system unless actual system level drivers were installed, but then this is an MSWindows machine, so all bets are off. I get the feeling that I am going to have to increase physical memory to half a gig - boy do I miss my Unix workstation!

It looks like you need a better PC. If you can't get a better pc, at least put more RAM. I would try a Pentium 4 with 1 G.
