After upgrading to 2.2.5.68 firmware, I've noticed that the Web UI ignores timeout settings and expires sessions very quickly. It's happening regardless of station or browser, while the SSH timeout is working as expected. This isn't isolated to a single unit, either: I have a pair (not stacked) that exhibit the same behavior.
I'm betting that this is a defect in the http server code; can anyone else duplicate or share a similar experience? This behavior is starting to drive me nuts, and I'm finding myself using the CLI more and more.
