Today an Accesspoint crashed when I wanted to connect on the serial line.
In case you have never seen an IOS backtrace, here we go:

No, I don’t know why a TCP process crashed when I connected via the console, at that time the Accesspoint was not even connected to the network.
And it looks like this is reproducable. Luckily there is a new version, so I will upgrade.
BTW, in February, for downlading the Accesspoint firmware or the Release Notes for the Accesspointfirmare, I only had to fill out a form, that I am not a terrorist and I will not use it against the United States. It looks like a terrorist abused this form by entering a fake name, because now a CCO account is required.
