Hello,

I got a very strange behaviour on my platform with the Xymon client. The cient process don't stop to change PID (and sometimes the process stops running without any reasons), I could see this behaviour thanks to Monit and here is an extract from the log :

CET Feb 14 14:28:29] info : 'xymon-client' PID has not changed [CET Feb 14 14:46:29] error : 'xymon-client' process PID changed to 2687 [CET Feb 14 14:48:29] info : 'xymon-client' PID has not changed [CET Feb 14 15:08:29] error : 'xymon-client' process PID changed to 21173 [CET Feb 14 15:10:30] info : 'xymon-client' PID has not changed [CET Feb 14 15:28:31] error : 'xymon-client' process is not running [CET Feb 14 15:28:31] info : 'xymon-client' trying to restart [CET Feb 14 15:28:31] info : 'xymon-client' start: /etc/init.d/xymon-client [CET Feb 14 15:30:31] info : 'xymon-client' process is running with pid 7355 [CET Feb 14 15:50:32] error : 'xymon-client' process PID changed to 24896 [CET Feb 14 15:52:32] info : 'xymon-client' PID has not changed [CET Feb 14 16:10:32] error : 'xymon-client' process PID changed to 10575 [CET Feb 14 16:12:32] info : 'xymon-client' PID has not changed [CET Feb 14 16:30:33] error : 'xymon-client' process PID changed to 28689

As a consequence each time PID changes, Puppet restarts Xymon client and after few hours I see a lot of hobbitlaunch process confusing some of my tests and filling up $XYMONHOME/tmp directory. I'm using Xymon for 4 years and never saw this before. My platform runs with Centos5.5 x86_64 and Xymon 4.2.3.

Why does Xymon change its PID like that ? Why does it suddenly stops running (no trace of segfault in logs) ?

This problem is now very annoying thus any ideas or advices will be appreciated J Sincerly,
