I installed Maple 13 and got some error, after quick search I find an answer
After installing Maple on my Linux system it doesn’t seem to work properly, it reports an error
“Error, cannot raise the datalimit above the hard limit”
This is most likely due to low virtual memory limits imposed by the shell process which is starting Maple.
By raising the virtual memory limit in the shell prior to starting Maple this can be avoided.
To do this enter the following in the terminal session starting Maple:
ulimit -v unlimited
The xmaple startup script in \bin\ can be modified to include this
I don’t understand what is virtual memory limit in the shell and how “ulimit -v unlimited” work?
If you can help I would be very 
I am using OpenSuse 11.3 32bit - Gnome.
