Program mysteriously STOPS!

[LJD]

Hi all:

The following code is designed (at least thats my intent) to run forever.  
The program should sit in a loop until it connects with the server.  It 
should just loop and loop and loop. 

It does, for a while, maybe five or ten minutes, but then the process just 
seems to vanish.  It's in the c1==0 loop when it quits. When I do a PS AUX, 
the process is just gone.  Obviously it quit, but more importantly WHY???, 
and what can I do so it doesn't?

Thanks,
Larry
