Unbounded frontend refresh queue can become a DOS attack when down route is restored

    Details

    • Type: Incident report
    • Status: Open
    • Priority: Minor
    • Resolution: Unresolved
    • Affects Version/s: 2.2.4
    • Fix Version/s: None
    • Component/s: Frontend (F)
    • Environment:
      Firefox web browser

      Description

      If you have a browser sitting on e.g. a screen with lots of graphs and the browser's route to the zabbix web server goes away for a period of time, refresh requests appear to queue up more or less without bound. When the route is restored these dequeue at a very rapid rate and can pretty effectively DOS all of zabbix with a severe IO overload. There really should be a bound on how many requests get queued up.
