My installation (30.000 Users, 30.000 Pics) crashes almost when trying to modify settings of Albums. If I look in mysql -> Processlist I get Millions of queries LOCKED because of something starting with:

| 290 | admin | localhost | comicfandb | Query   | 76   | Copying to tmp table | SELECT aid, IF(username IS NOT NULL, CONCAT('(', username, ') ', title), CONCAT(' - ', title)) AS ti |

All other queries behind this one are locked, I think this one makes a query to cpg_pictures and nuke_users at the same time. Please HELP!

I found this one in modifyalb.php:

$sql = "SELECT aid, IF($field_user_name IS NOT NULL, CONCAT('(', $field_user_name, ') ', title), CONCAT(' - ', title)) AS title " . "FROM {$CONFIG['TABLE_ALBUMS']} AS a " . "LEFT JOIN {$CONFIG['TABLE_USERS']} AS u ON category = (" . FIRST_USER_CAT . " + $field_user_id) " . "ORDER BY title";

this seems to be a killer query. Joining two tables without using indexes in the JOIN field and ordering without index. It is running minutes and the worst:

It locks all other queries to the cpg_albums and nuke_users table....

Is there any other way????

This code does not appear in coppermine 1.3.0 standalone, and as you seem to be running a nuke site, I suspect you have the nuke version of coppermine(at least you should have).
For coppermine for CMS support you should go to
It has been a long time now since I did my little bit here, and have done no coding or any other such stuff since. I'm back to being a noob here
