The only time that virtual memory might enter into the problem is if
the kernel itself crashes. Other software crashes should be accompanied
by a core file (unless you have that suppressed) which should give you
some information as to why there was a failure. The stats you included
are not indicative of a problem, and it appear that you have 11GB of
virtual memory to play with, where almost none of it is in use.
You might get a better indication by executing the "swap -l" command
(if you have it) which will tell you swap usage.
