Re: More on DDOS Attacks

I had a customer with a 2610 running 12.0(4) that had constant random "spurious memory access" errors. I advised him to upgrade to upgrade to 12.0(5) but haven't heard back. Cheers, Andrew Donald Neal wrote:

I've been meaning to have another try with a newer version of 12 (especially as 12 has gone GD) so your experience is only going to encourage me, can I ask what version of IOS and on what platform you lab setup was using? [clip] That's not to say it is very stable, the last I tried 12.0.7(S) was pretty horrible. I have '9 down but not tested yet.

Speaking of the stablity of different IOS versions, we have a 3640 with 12.0(4)T on it that needs rebooting after about 7 weeks of uptime. Starts spamming the console port with memory allocation failures, although still manages to route stuff.

It's not a particullarly odd setup, just routing between a couple of FE ports, but we are using dynamic packet filtering on it, ala "permit ... reflect outbound".

Ring any bells for anyone? Couldn't see anything that jumped out at me in the later release notes, and wasn't keen on an upgrade just to "try it out"..
