Is there someway I can determine the filenames of all the currently
open files?

I have an application that, after many hours of running, dies when
I try to open another file. The error is something like, "too many
open files."

It is our application, but we are calling a number of third party
library routines (GSS CGI is the main one) that open and (hopefully)
close temporary files. 

We cannot track down any place where we open a file and don't close
it, so we are beginning to suspect the other library routines. One
of them is possibly not closing some temp file. But who?

Any suggestions?

Thanks,
  -Larry.
