KACE: Limiting Closed Port RST Response from X to 200 Packets/Sec

Summary:

After scheduled downtime, a reboot, or anytime the web service of the appliance is unavailable for an extended period, the web interface may become inaccessible, and the konsole will display the error message "Limiting Closed Port RST Response from X to 200 Packets/Sec."

Issue:

This error message indicates that the K1000 Appliance is getting more than 200 packets per second on closed ports, and will occur when a large number of clients attempt to connect to the appliance at the same time.  The threshold of 200 is a limit built into BSD.

 

Resolution:

As the web service on the appliance is brought back up during the boot process, and agents begin to connect, the konsole messages should subside, and the web interface will again become accessible.

 

Web interface inaccessibility and delays to the boot up process, caused by the konsole messages, may be prevented.  Removing the appliance from the network, or simply removing the network cable until after boot up has completed, should prevent further issues.

Comments

  • It can also happen if one process is lasting for a long time during the boot.
    Usually if a database check is performed on a huge database or similar.
    if this is the case, you should verify if there is a possibility to shrink the database.

    Also, of course if a "security run" on the network checks for open ports (from admin or from an intruder) this can happen. - Nico_K 7 years ago
