does anyone know what causes error numbers -1074360311 and -107436010?

[stewbert]

Hi,

I'm getting random occurances of error numbers -1074360311 and -107436010, they seem to be linked to acquiring images from some firewire cameras but i'm struggling to track down the cause. my system can run for hours without the problem. When it errors it can sometimes require a full system shutdown and re-boot to clear it.

I have also noticed that sometimes when the error occurs one of the cameras is missing from the MAX list (there are 8 cameras in total running through powered hubs).

Thanks for you help,

Stewart.

8 cameras????????Defenitely bandwidth problem.You can download the bandwidth monitor from ni.com.I had the same problem while using 3 firewire cameras.

It Shouldn't be a bandwidth issue as they are aquired from sequentially, not in parrallel.

Check the buffer name?

Can you post your code?

[stewbert]

It's a bit difficult to upload just that section of the code, however heres a description of how it works:

1. open connection to all cameras

2. run main code

3.snap image from each camera in sequence

2. run main code

So the connection to the cameras are only opened once in the initialisation section. the connection is only closed on program exit.

I have linked the error to only occuring if no images have been taken in about 20mins, it is almost as if the connection to the cameras is closing itself of windows is dropping a camera.

Hope this is of some help.

So seems to be a time out error.Connect the error out to simple error handler and chose no dialog.Hope it works!!!!!

i wish it was that simple! the pc requires a re-boot or i must re-start labview before it will work again.

Well I really require the code to suggest any improvement.Atleast a snap shot of the block diagram will be of grt help.R u sure the cables are absolutely fine?

[stewbert]

here are the initialise and main acquire vi's.

It's definatly not a cable problem as i have two seperate systems running the same setup and code and get the same problem.

Stewart.
