[CentOS] Where to look or command

List,

    I've got a process(s) that have been exiting on a signal 11, but not 
all the time.  I suspect it's memory related, and I was wondering, is 
there any way to tell exactly how much memory a particular process has 
in use at the point it sigsev's ?  I can't sit here and watch top or the 
system monitor, but thought maybe something might be saved somewhere 
after the fact.  The processes are using at the moment, 1.4gb of memory 
and no swap.  I've not seen swap go active during any of this process 
run, and the machine has 2 GB memory installed.  Rather hard to trace 
down the exact activity when it happens.

Thanks..
