[smokeping-users] slave child probes never die

[David Behr]

Hi

 

The probe child processes on my slaves keep multiplying after a master
change.  Over time they grow to hundreds of processes.

 

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.

 

Here are the logs:

 

Mar 26 17:59:24 rs5 smokeping[16662]: Smokeping version 2.003003
successfully launched. 

Mar 26 17:59:24 rs5 smokeping[16662]: Entering multiprocess mode.

FPingNormal. 

Mar 26 17:59:24 rs5 smokeping[16662]: All probe processes started
successfully.

 

Now ps shows:

All is ok, now I change the master config and slave gives:

 

Mar 26 18:06:12 rs5 smokeping[16663]: Sent data to Server and got new config
in response. 

Mar 26 18:06:12 rs5 smokeping[16663]: server has new config for me ...

FPingNormal. 

Mar 26 18:06:14 rs5 smokeping[16663]: All probe processes started
successfully.

 

The child probe called "EchoPingSmtp " now starts a new process (17161,
17162 and 17163) for all the probes. but look at ps now:

 

root     16662  0.0  0.5 19176 11796 ?       Ss   17:59   0:00 /usr/bin/perl
-w /usr/local/smokeping/bin/smokeping --slave-name=rs5
--master-url=http://XXX/cgi-bin/smokeping.cgi --cache-dir=/tmp
--shared-secret=/usr/local/smokeping/etc/secret.txt

The old children are still hanging around.

 

After just 2 master changes I now 25 smokeping processes running!

 

Am I doing something silly or could this be a bug?

 

Thanks
