Yesterday we experienced a problem on the core-routing system at 14:05 CET in Munich, after controlling all cables, electricity and running diags on the linecards, we had to perform a cold restart of the router to get back online. We’re still investigating the cause of this problem, most probably a software-bug with the Cisco 12016 GSR IOS. After one hour and 40 minutes all systems were back online and fully operative.
Ieri alle ore 14:05 CET i sistemi di core-routing hanno cessato di funzionare a Monaco. Dopo aver controllato cavi, cablaggio, elettricita’ e le varie linecards, abbiamo dovuto togliere e rimettere la corrente al router per ritornare online. Stiamo tuttora indagando la causa esatta del problema, probabilmente si tratta di un software-bug del sistema IOS del router Cisco 12016 GSR. Dopo un ora e 40 minuti tutti i sistemi erano di nuovo online e ripristinati.
Gestern um 14.05 Uhr CET kam es zu einem Totalausfall des Core-Routing-Systems in München. Nachdem wir Kabel, Elektrizität und die versch. Linecards (Hardware) kontrolliert haben, war ein kalter Neustart des Hauptrouters notwendig, um wieder online zu kommen. Wir prüfen immer noch, was die genaue Fehlerursache war, höchstwahrscheinlich ist ein Software-Bug im IOS-Betriebssystem des Cisco 12016 GSR Routers verantwortlich, da keine Hardware-Fehler gefunden wurden. Nach einer Stunde und 40 Minuten waren alle Systeme wieder online und operativ.
[UPDATE]: The problem was due to a heavy increase in the BGP-table, the memory was upgraded. Additional processor memory has been ordered and will installed within 2 weeks.
