OK, dumb, dumb, dumb.
Its been a long time since I looked at this thing, but in fact the file argument
IS hardcoded,- the argument is the name of a FIFO that the program will
write to later on.

Starting program: /mnt/i1/Images/bin/zap3a
Program terminated with signal SIGKILL, Killed.
The program no longer exists.
You can't do that without a process to debug.

Here is the result of the current limit command
[reg@deneb bin]$ limit
cputime unlimited
filesize unlimited
datasize unlimited
stacksize unlimited
coredumpsize unlimited
memoryuse unlimited
vmemoryuse unlimited
descriptors 1024
memorylocked 32 kbytes
maxproc 16368

And the top of the program, other than limits things its hard to
understand what its complaining about before getting to the
first print statement...

Any more thoughts?
Mabe Im just not seeing something.
