SWarp cannot find resampled file

[tiger12896]

I am making a stack of 100+ images using SWarp.  Each time, it resamples all of the images, but then at the end, it comes in and says it can't find one of the resampled files.  I have tried removing the specific image from the stack, but the same problem comes up again with another image.  Here is the error:

-------------- Co-adding frames            
Maximum overlap density: < 135
> Reading   line:    527 / 2788  
> *Error*: cannot open for reading ./bootes1.6974s.resamp.fits


I have pasted in below the command line argument I used to run SWarp.  Thanks for any help.

The command line didn't come out so well in my previous post, here it is in attachement form.

Furthurmore, I have noticed that the error occurs on line 537 each time.

Sorry, line 527

Hi Stephen,

This is for sure a 'grand classique' with SWARP. What is the maxium number of open files allowed by your system? If you do 'limit' you will see a number for 'descriptors' which is usually set too low. swarp needs to keep a large number of files open during resampling. Play around with the 'limit' command to see if that fixes it. There is a way to set things permanently, but I can't remember it offhand right now.

cheers

That fixed it, thanks! There is one more problem, but it is closely related to another thread, so I'll reply there.
