Wazuh-agent is block connections

[doc dodo]

Hello,

After restart Wazuh-manager my Wazuh-agent reconnected to server, but application on server  Hello, After restarting Wazuh-manager, my Wazuh-agent reconnected to the server, but the application on the server stopped working correctly.

The application began reporting errors connecting to the database server:

2026-07-16 16:34:50,839 INFO  [stdout] (default task-3479) [07:16 16:34:50.839] [ERROR] [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] - javax.resource.ResourceException: IJ000470: You are trying to use a connection factory that has been shut down: java:/jboss/datasources/OracleAPP
2026-07-16 16:34:50,873 INFO  [stdout] (default task-3479) Caused by: java.sql.SQLException: javax.resource.ResourceException: IJ000470: You are trying to use a connection factory that has been shut down: java:/jboss/datasources/OracleAPP

This error was generated until the Wazuh-agent was rebooted.

How can an agent influence the operation of network connections?

Hi doc dodo,

A restart of the Wazuh Manager does not alter network connections other than its own in any way.

Can you share your Wazuh Agent's ossec.conf file at /var/ossec/etc/ossec.conf or C:\Program Files (x86)\ossec-agent\ossec.conf for review?

This would help me understand if there is any relation between your application and the Wazuh Agent.

Regards,

Fede

I attached the config to the letter. 

Thanks.

Hi doc dodo,

I don't see anything wrong in the configuration. I was looking for custom integrations or recurring commands that might be reserving ports for themselves, but it doesn't seem to be the case. Is this problem something you can reproduce?

If so, can you give me detailed steps on how you reproduced them?

Just so I can try that here and look for a cause and a solution.

Regards,

Fede
