Memory problems

Sat May 11 22:37:01 2002

THanks for your help.  Everything worked as stated (except you need 
/sbin/mkswap, but that is a minor detail).  However it still did not solve 
anything.  I already had a swap area and expanded it to about 600MB.  I am 
wondering if there is something in the YDL 2.2 memory allocation or 
something like that that is causing things not to work.  Meaning that this 
a problem within the java runtime.

One quick question.  I would like to test a theory, but I was wondering how 
to I stop X.  I keep trying to kill it and it just restarts.  I am thinking 
that maybe X is taking too much memory and just see if java runs at 
all.  What do I need to do?
