Hello,

Just installed pt-kill 3.0.3 on CentOS 6.8, and it won’t kill long queries (timing).

I ran the command below (it prints the correct query, but won’t kill it and keeps repeating same printing as before):

pt-kill --busy-time 30 --user dbuser -p ‘dbpassword’ --interval 3 --print --kill-query

How can I solve this?
