Mysql: status procesu

Pokud si dam vypsat procesy mysql (mysqladmin processlist) tak se mi tam obcas objevi proces se statusem "Statistics". Jedna se o Select. Pokud se nasledne jiny proces pokusi zapsat do tabulky, ze ktere byl ten Select, tak ma status "Locked". Tim se pak blokuji ostatni Selecty z dane tabulky (cekaji na ten Insert/Update) a pak je jen otazkou casu nez pocet procesu se statusem "Locked" prekroci maximalni mez.

vypada to asi takto (ty dotazy jsem zkratil aby to bylo kratsi):

+-------+------+-----------+----+---------+------+------------+---------------
| Id    | User | Host      | db | Command | Time | State      | Info
|+------+------+-----------+----+---------+------+------------+---------------
| 17694 | web  | localhost | db | Sleep   | 236  |            |
| 17947 | web  | www:37227 | db | Sleep   | 0    |            |
| 19412 | web  | www:38985 | db | Query   | 81   | statistics | SELECT count(id) FROM katalog ....
| 19645 | web  | www:39285 | db | Query   | 1    | Locked     | UPDATE katalog SET ...
| 20039 | web  | www:39732 | db | Query   | 1    | Locked     | SELECT ... FROM katalog ... 
| 20040 | web  | www:39734 | db | Query   | 1    | Locked     | SELECT ... FROM katalog ...
