      Description

      We have several hundreds of windows hosts and on some of them after trying to stop/start "zabbix agent" port 10050 is not released and there are a lot of "time_wait" connections, so service coudn't be started until we reboot the machine. Via TcpView it is possible to close "time_wait" connections but not that which is in listening state and it shows <non-existent> process.

       

       

      C:\Windows\system32>sc query "zabbix agent"
      SERVICE_NAME: zabbix agent
       TYPE : 10 WIN32_OWN_PROCESS
       STATE : 1 STOPPED
       WIN32_EXIT_CODE : 1067 (0x42b)
       SERVICE_EXIT_CODE : 0 (0x0)
       CHECKPOINT : 0x0
       WAIT_HINT : 0x0
      C:\Windows\system32>netstat -ano | findstr :10050
