LabVIEW 2009 freezes when saving vi

[pawel]

Hi

My LabVIEW 2009 v 9.0f2 (64-bit) freezes for 20seconds every time it saves vi.

Anybody seen that?

Is there a fix to it?

thanks

Watch your CPU and processes while that is happening. It is either normal or possibly Virus checking code is involved.

ProcessMon (name) available from MS will let you trace OS calls if you really want to get to the bottom of it.

Thanks Ben

The processor is at 12% and the only process taking this much is LabVIEW :).

I cannot even disable virus scanner as IT have blocked it.

I will keep looking

thanks

OK, found it.

This time LabVIEW cannot quickly save the graphs with large data in it. When I limit or remove the graph the saving is quick.

It is still anoying, but at least I can woek now.

thanks

For a real thill along the same lines search this site for the terms "Ben Mouse Tendon" find that sample code and run it. I have seen that chug for an hour or more before LV crashed giving my an end of file error which I interpreted as "this VI is to large fo rthe file system to support!"

If your CPU was showing low load the delay may have been while try to allocate space. Check you disk fragmentation.

Sorry, could you clarify:

• Do you have graphs with huge amounts of default data?
• Do you have charts with huge history sizes?

Unless the graph data is the default, it will not get saved with the VI and I don't think it should slow you down.

How big is the VI on disk (the one that saves slowly).

Hi

Good guess.

When the default data arte there the vi size is 12MB and LV chokes.

When I clear the graph and resave the vi is 1.5MB and the saving is instantenous.

The thing I will need to rememmber is not to use the Edit->Make values default, as it will make again the problem come back. I will use the local control "make default" option instead.

thanks a lot
