<p class=MsoNormal>Hi<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The probe child processes on my slaves keep multiplying
after a master change. Over time they grow to hundreds of processes.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>It appears that each slave probe that gets a new config,
spawns a whole new set of children - but the old ones never go away.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Here are the logs:<o:p></o:p></p>
