Well here is an interesting piece I will add to this. All was fine before I left for Christmas holidays. I returned home fired up the computer and joined a server some of my other clan mates were in. About 5 min in I got kicked for the exact same thing (len=2048). I know my server is running all the MD5 and CVAR checks so I joined it and ran around for about 15 min with no problem at all. I rejoined the server my guys were in and again I was kicked for the same thing.
This has only happened on the one server so could it be a bad setting on the server that could be causing this?
I am not worried about it, I just find it odd that I changed nothing and got booted from this one server.
