I sometimes find that when I run a process that I know uses up a great deal of system resources, it terminates unexpectedly. Is this because it becomes unresponsive, or is it because Ubuntu can't cope with the demands? Is there a way to circumvent this, for example, by increasing the virtual memory? If so, how?
Note that I am running Version 11.04 of Ubuntu on a single Pentium 4 processor with 4GB of RAM. If it's any help, my computer is a DELL Optiplex 210L.
