I am having problem with /usr/sbin/makemap hash on huge databases
under FreeBSD 5.5 and 6.3 while it is working on 4.11.

By huge I mean around 380,000 lines in the /etc/mail/access file.

After approximately 375,000 lines added into access.db I get:

makemap: access.db: line 375135: key abcd.efgh: put error: Operation not permitted

and no more line will add.

I know that having 380,000 REJECT rules in access.db may not be the
best choice, but it is easy and it was working si far (still works
under 4.11).

Did anything changed in makemap since 4.11? Any limit in the size of
the DB?

It seems that my message yesterday was zapped by SpamAssassin (because
I included names of infamous spamers as part of my examplke), so I
rewrote it.

I am just under 300K lines in that map at present. While I have always wondered where hash was going to break, I hadn't found the limit yet. However, the time to build the hash table is extremely large with that many entries. I ran some tests a couple months ago using btree for the map type (subject was 'Map size'). I didn't test over 300K entries, but it sure built the maps a whole lot faster. You might try that and see if it builds or not.
