As I understand it, CVS requires at least 2x the file size in available memory 
to process a file. 2x70MB = 140MB > 134MB.

Well, regarding allocating memory - I was able to 
write a small C program which was able to malloc()
upto ~134MB - It gave a pointer back, and i was able 
to write to all of it without any signals. Then why 
do you think CVS is having trouble with a 70MB file?
If a simple program has access to 134MB, wouldnt that
be sufficient for CVS for handling a 70MB file? Please
do let me know if you think there might be other 
bottlenecks on the systems resources.

Which is why i wanted to ask this list if there 
was anyone with an AIX machine handling more than 
70MB - so that I get an idea of how they configured
their system to get it to work.
