sa-learn --rebuild

[Kris Zabriskie]

When I try to run "sa-learn --rebuild" via crontab at midnight.  I get this
error:

Failed to create default user preference file://.spamassassin/user_prefs

............................................................................

expire_old_tokens: Out of memory during "large" request for 1052672 bytes,
total sbrk() is 133331264 bytes at
/usr/local/lib/perl5/site_perl/5.6.1/Mail/SpamAssassin/BayesStore.pm line
390.


Does anyone have any ideas on what direction I should start looking in?  As
always, any help would greatly be appreciated.
