As a potentially useful data point, I am running milter-greylist-4.2.2 
on Solaris 10 U6 (+patches) SPARC with libspf2 1.2.9 and after 126 
days of uptime, it is consuming only 36MB of RAM, with no sign of a 
leak.

My greylist.db is only 1.5MB.  When greylisting was first employed, 
the file was much larger but it seems that over time, the amount of 
spam attempts has considerably diminished.

It could be that the connection rate is overflowing an arbitrary limit 
on 32-bit Solaris.  I recall something in the notes regarding a file 
descriptor limit.  Unfortunately, libmilter is not provided as a 
64-bit build under Solaris and it is more work to build your own.
