ps gives error

[Cathy Accettura]

I am having problems tracking down a problem.  That
we appear to have every afternoon.  When I try to do
a ps I get not enough memory.  When I do a df I get
not enough core.  I don't see anything in crontab that
is causing the problem.  I can do a pstat but I don't 
know what I am looking for.

I need some tools to find out what the problem is.

I have a MicrovaxII runing Ultrix 3.0.
