after updating Nagios Core from 4.4.3 to 4.4.4 I observe an increasing number of "defunct processes" (zombies?).
Code: Select all
22331 ? Z 0:00 [check_nrpe] <defunct>
22332 ? Z 0:00 [check_ssh] <defunct>
22333 ? Z 0:00 [check_nrpe] <defunct>
22348 ? Z 0:00 [check_nrpe] <defunct>
[and so on]
- Nagios Core 4.4.4
- Red Hat Enterprise Linux 7.7
- 300 monitored hosts
- 6500 monitored services
The system load has NOT increased.
When stopping Nagios Core (systemctl stop nagios.service) all "zombie"-processes vanish immediately.
In the Nagios Release Notes (https://www.nagios.org/projects/nagios-core/history/4x/) I can find the following information:
I wonder, if this "fix" has made things worse. This behaviour does not seem to be intended, right?Fixed defunct worker processes appearing after nagios was reloaded (#441, #620)
Does anyone here face the same issue?
Best Regards
C.I.
