R help - Jan 2012 - arules "killed"

Hi, I recently got a bizarre message when running arules. It just said
"Killed" and quit. Anyone know why this might have happened? I am
running R
on an AWS quad xl ubuntu instance.

Here is some information, including dataset size and the parameters:

parameter specification:
   confidence minval smax arem  aval originalSupport      support minlen
maxlen
 0.0003581251    0.1    1 none FALSE            TRUE 3.581251e-05      2
   4
 target   ext
  rules FALSE

algorithmic control:
 filter tree heap memopt load sort verbose
    0.1 TRUE TRUE  FALSE TRUE    2    TRUE

apriori - find association rules with the apriori algorithm
