RELEASE_LOCKOWNER(old clid) ----->
<--- expired error
RENEW(old clid) ----->
<--- expired error
SETCLIENTID ----->
<--- a new clid
SETCLIENTID_CONFIRM (new clid) -->
<--- ok
RELEASE_LOCKOWNER(old clid) ----->
<--- expired error
RENEW(new clid) ----->
<-- ok
RELEASE_LOCKOWNER(old clid) ----->
<--- expired error
RENEW(new clid) ----->
<-- ok
