<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>I think I'm
experienceing a problem with runaway child processes. I read the FAQ and found
the service_reaper_frequency entry... But I don't think that's the problem (I've
set it to 4 just to be sure)</FONT></SPAN></DIV>

<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>A little about my

<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>I'm
monitoring several hundred machines, and a couple thousand serices on these
machines.</FONT></SPAN></DIV>
<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>I'm doing this using
the passive method. (piping to the nagios.cmd file) I dump the results of the
other monitoring processes into nagios.cmd every 5 minutes</FONT></SPAN></DIV>

<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>The first couple of
hours after startup, things appear to operating fine, with no more than 5 or 6
nagios child instances running at any given time, and no instance running for
more than a couple of minutes. </FONT></SPAN></DIV>

<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>Sometime after the 2
hour mark, the child instances take long and longer to complete, if they
complete at all (upwards of 20 min and higher). And these processes just start
building up.</FONT></SPAN></DIV>

<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>I can attach to
these processes using strace and they all appear to be doing things once i do
that, but it's almost like the mere act of observing these child processes makes
them complete (whereas if i just let them go, they would never finish), but
other child processes are truly "hung/slow-as-mol". </FONT></SPAN></DIV>

<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>I can kill these
processes fine, but I can't forever monitor these processes to make sure they
don't get out of hand. </FONT></SPAN></DIV>

shed on this would be greatly appreciated:</FONT></SPAN></DIV>

<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>1) why is nagios
spawning these child processes (i'm passively monitoring)</FONT></SPAN></DIV>
<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>2) why are they not
finishing (and this behavior is only visible after a few hours of
running)</FONT></SPAN></DIV>
<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>3) how can i prevent
this from occurring?</FONT></SPAN></DIV>
<DIV><SPAN class=333165823-22112006><FONT face=Arial size=2>4) could it be that
something is hanging the process and by the time it becomes unhung, the child
reads a new dump from the nagios.cmd file, and thus never ends (i don't even
know if that's what the child processes are doing - the strace
reads:</FONT></SPAN></DIV>
