mmap: Cannot allocate memory

[Shannon Scott]

Greetings,
I have a program that manipulates data for me on a linux server.
Recently when I try to run the program, I get the following error:
mmap: Cannot allocate memory
 
This happens immediately after starting the program, but the system has
1Gig of RAM.
 
Has anyone else experienced this issue?
Can anyone provide insight into the cause of this problem?
 
Thank you for any help or pointers.
