Hello, I have a DistantPoller that failed it’s centengine service with this error:

I don’t know exactly what means “centenginee924]: free(): invalid pointer” or how to discover what causes it. But the load, RAM use and Disk seems to be ok.

I saw this error because y saw that in the las DistantPoller the Last Update showed in yellow.
 


These are the last lines of the centengine.log:

¿How can I dig more in the cause? ¿what files or commands can I use to discover the causes?

PD: Sorry for my bad english, if you have doubts about what i want to express let me know 😉

Hello ​@ruben_mendez 

This can explain the color

 

#2 The last update time is older than 15 minutes and highlighted in yellow:

 

and this could help with the other

and

 

 

Check the status of processes 'cbd' and ‘centengine’.

By overriding the --process-name option with the '^(cbd|centengine)$' filter, I include cbd and centengine processes in my command line

-bash-4.2$ /usr/lib/centreon/plugins//centreon_linux_snmp.pl --plugin=os::linux::snmp::plugin --mode=processcount --hostname=10.25.5.88 --snmp-version='2c' --snmp-community='public'  --process-name='^(cbd|centengine)$' --process-path='' --process-args='' --regexp-name --regexp-path --regexp-args --warning='' --critical='1:' --cpu --memory --verbose
