Description Gilbert Cahute 2020-02-12 17:18:39 UTC 
We are experiencing a memory leak in nagios when using external brokers.


Description of problem:
The nagios process will grow into several gigabytes of RSS over time, eventually needing to be restarted and force kernel to drop caches
( sysctl -w vm.drop_caches=1 )

Version-Release number of selected component (if applicable):
Name        : nagios
Arch        : x86_64
Version     : 4.4.3
Release     : 1.el7

How reproducible:
Always.

Steps to Reproduce:
1. Use mod_german external broker,
2. Monitor memory usage over time,

Actual results:
Nagios process' memory grows over time, then uses swap.

Expected results:
The nagios process memory usage should remain stable after a temporary startup stage.

Additional info:
Linked comment shows upstream resolution, "added to the 4.4.4 milestone on Jul 24, 2019" but 4.4.5 may be a better candidate ^^
