Yes, milter-greylist has some memory leaks, at least with some 
compilation options.

I have set up a cron to restart it every time it hits the 1GB VSZ limit. 
This orrcurs at various rate depending on inbound traffic but roughly at 
least once a week. Once restarted (and database reloaded), VSZ drops to 
about 100MB, so the tuple database is not the reason.

I'm on linux Debian (Sarge with Etch libc6/kernel) and configure 
milter-greylist 4.0 (with some additional patches, but this didn't 
impact the memory leak problem) with:
./configure --prefix=/usr/local --bindir=/usr/local/sbin 
--sysconfdir=/etc --localstatedir=/var/lib --enable-dnsrbl --with-libspf2_
10=/usr/lib --with-conffile=/etc/mail/greylist.conf 
--with-dumpfile=/var/lib/milter-greylist/greylist.db 
--with-libcurl=/usr/lib

Since I have this "automatic diet" cron job and the machine has plenty 
of RAM, I never worried too much about this memory problem, but it still 
exists...
