Agents disconnect from manager without reason

[okynos]

Wazuh version	Component	Install type	Install method	Platform
v4.1.5	remoted	Manager and Agent	Packages	CentOS 7

We have detected that Remoted or agentd lost their connection with each other in specific cases.
The agent seems that can't connect to the manager within 5 hours.
Here we put all the obtained data from the agent and manager.

Suspicious logs that repeats 7 times inside the manager log:

2021/05/02 14:32:03 ossec-remoted: INFO: (1409): Authentication file changed. Updating.
2021/05/02 14:32:03 ossec-remoted: INFO: (1410): Reading authentication keys file.

Evidences:
Manager memory decreases during hours (RSS) ->
Same behaviour at agent side same hours (CPU) ->

The rest of the information:
agent_centos_2.tar.gz
agent_ubuntu_3.tar.gz
manager_centos_1.tar.gz
