    Description

      On the server we use Zabbix ( version 5.2 and after that we upgraded to 6.4.beta1) and have a dayly backup usung Synology NAS .

      Each day ( after the backup) server did not respond and require manual restart.

       After the investigation from Synology support team they found that  Zabbix does not release system resources properly.

        Synology NAS process go to use the semaphore of per CPU. But because of Zabbix, the semaphore has not been released, causing the Synology NAS process to get stuck

      Steps to reproduce:

      1. You need to have Synology Active Backup for Business agent installed on the server
      2. Scheduled backup for each day.
      3. Wait for the backup
      4. Server will stuck

      Result:
      Server not respond to all
      Expected:
      Correct released of  the semaphore  per CPU
