      Importing new templates failed even after 30 min with "lock wait timeout" MySQL error. That takes minutes on 2.0, and become worst after upgrading on 3.0.
      One of a possible point is ids table and audit, noticed that during importing several times was blocked transactions with query DETETE from ids where table_name='auditlog', which must rise only when reached maximum ID.

      private static function refreshIds($table, $count) {
                      $tableSchema = self::getSchema($table);
                      $id_name = $tableSchema['key'];
      
                      // when we reach the maximum ID, we try to refresh them to check if any IDs have been freed
                      $sql = 'DELETE FROM ids WHERE table_name='.zbx_dbstr($table).' AND field_name='.zbx_dbstr($id_name);
