Hello, using postfix 2.8.2 under Solaris 10 with postscreen_cache_map = dbm:$data_directory/verify_cache
it appears that cache cleanup logging gives erratic numbers of retained entries, ranging between 1875 and as high as 727916: Apr 3 11:32:25 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=1875 dropped=59 entries Apr 3 23:32:58 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=468417 dropped=693 entries Apr 4 11:33:13 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=238015 dropped=1087 entries Apr 4 23:33:43 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=404255 dropped=207 entries Apr 5 11:34:08 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=357344 dropped=1094 entries Apr 5 23:34:09 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=10043 dropped=278 entries Apr 6 11:34:24 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=235581 dropped=1393 entries Apr 6 23:34:52 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=389771 dropped=839 entries Apr 7 11:35:41 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=668060 dropped=546 entries Apr 7 23:36:23 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=569135 dropped=903 entries Apr 8 11:36:41 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=259013 dropped=1148 entries Apr 8 23:36:59 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=252607 dropped=832 entries Apr 9 11:37:08 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=117216 dropped=677 entries Apr 9 23:38:02 postfix/postscreen[760]: [ID 197553 mail.info] cache /var/lib/postfix/verify_cache full cleanup: retained=727916 dropped=492 entries The actual number of cache entries on this system is around 25000: # postmap -s /var/lib/postfix/verify_cache | wc -l 24436 Otherwise postscreen is working well, so if this is a bug it would only be minor. -- Peter Schultze
