Milter-greylist

Hello,

after ten days of operation milter-greylist uses 1.8 GB virtual
memory with some estimated 50 to 100 MB more per day, but greylist.db
has only 42 MB.
If this is expected behaviour, we would plan an automatic re-start.
When to restart best?

Using 4.0a1, x86_64 SuSe Linux 10.1, dnsrbl and extended regexp configuration.
