That, or some process is requesting a large amount of memory, or spawning
multiple copies of itself, the total requirement being more than the
available virtual memory of the system.
Monitor the process usage by displaying top in a shell window. Press M so
that top is sorted according to memory usage. Watch the display and see if
you can determine which process is growing.
Of couse, the memory problem may only be triggered by a particular event, so
you might have a long wait...
