pitchfork (gen:0) worker[3] - requests: 6684, waiting
pitchfork (gen:0) worker[2] - requests: 14756, waiting
pitchfork (gen:0) worker[1] - requests: 97007, waiting
pitchfork (gen:0) worker[0] - requests: 2229848, waiting

In a more serious note, the one doing all the work has just 100MB RSS over the average? Looks normal to me, or am I missing something ?
