use DB_File::Lock; use Fcntl qw(:flock O_RDWR O_CREAT);
and opening the DB with the command:
$db = tie %GDB, 'DB_File::Lock', $DBFilename, O_CREAT|O_RDWR, undef, $DB_HASH, 'write';

All,
I turned on greylisting last night, based on the code posted by Steve Rocha (which was based on Jonas's code i think). Things were fine until the db reached about 3300 records. Then it would not accept any new keys, the inserts just silently fail. I turned off greylisting and verified this... it appears the db is corrupt.
Could this be caused by a locking issue? Right now the lock_db function is just using flock before tie'ing the hash:
lock_db(); if (tie(%GDB,'DB_File', $DBFilename)) {
Is this safe? It is a moderately busy mail server, around 150k messages a day. Is this too much for a dbm file? I'd imagine i'd have 10's of thousands of triplets in the db. Should i look at implementing it in mysql or postgres?
And just for my curiousity, is there a way to repair a corrupt dbm file?
