Has anyone seen this error?
Phar Lap fatal err 10049: Ran out of stack buffers

It started today on this program I'm working on. It doesn't happen all the time to it's to track down. The error is displayed out on the dos level.

The only thing I'm doing different than any other program I write is that in the prg I have a function defined rather than procedure. Is there some limit on open files and the number of calls to other procedures that I can do from within that function? Any arrays and variables I'm using are released as soon as I'm done with them. So I can't see where this memory issue is coming from.
