Out of Memeory error with ezmlm 6.0.1

Hi - just installed 6.0.1 and created a new list with:

ezmlm-make -agmuri -5 [email protected] 
/usr/local/sites/www.bentrutwin.com/users/blogannounce 
/usr/local/sites/www.bentrutwin.com/.qmail-blogannounce
blogannounce bentrutwin.com

Sent a test message and this was in /var/log/qmail/current (sorry for
the wrapping)

System has plenty of available memory (especially on a Sunday night)
