IOS bug of the day

It's a competing philosophy and management is taught to err on the side of making money when it comes into conflict with security or stability.

"The system will crash in 3 days if we don't reboot it now!"

"Then let it crash and reboot it then, we gotta make fat stacks of cash until then!"

We're already on 9.2 something. It was a cluster and for some reason the secondary unit stayed operational so we rebooted after business hours. We are extremely grateful to Cisco for another 7 months of uptime now.

In that case you would need 9.2(4)15 and higher to resolve the bug

I saw ristau5741 reply, and knew exactly which bug it was. That sucks. Were you able to recover?

So which system is it now we can't use Chrome for?

NVM, looked it up. ACS. Ouch. I was at one of the first companies to discover THAT disaster...

I also remember we had an issue with Firefox and CUCM at one point(maybe 10.5?). Not corrupt database bad, but it didn't work.

Yes, fortunately it was only the TACACS+ ruleset, which only had 7 rules which I wrote myself so I remembered

There was that legendary ACS bug where if you used a certain (very common) version of firefox and clicked on something it would literally explode the entire database.
I had a customer resort to recovering their entire ACS from backup as a result of an admin simply clicking around the interface in firefox.

It was something similar

Basically, the message is this: Cisco dev teams pretty much use one and only one browser for testing, so be sure to match the browser with the product. Different teams will use different browsers (and Java versions...) so one size does not fit all!
