[rt-users] Identifying sessions

Hi list,


we've been having some issues with RT (4) becoming very slow at times. By using mytop, I've realised that there are often SQL sessions showing up as "slow" or completely froze such as:


577   rt_user       localhost        rt4       234  Query SELECT GET_LOCK('Apache-Session-d5370769b644a8e12a7df739cf100b8a', 3600)    ?



This one, with process id 577, never goes away for example. Others appear and disappear.


How can I identify what's running this session? I suspect this might be linked to some users running heavy searches, and what I read online in the archives seems to confirm the suspicion.


Any idea would be welcome.


Thanks,

Giuseppe
