We have released a Beta update for Counter-Strike 1.6. 
Changes in this update are: 
...
Increased default cl_cmdrate value to 60 
Increased default cl_updaterate value to 60

I start a local HLDS, join on it, then I restart the server with restart command, and client gets kicked off with CMD_MAXBACKUP hit message server console:

Everything was working yeasterday

Also, the problem appears on changelevel

Are you sure that's not a plugin with the server you're playing on?

BTW @alfred-valve it might be a good idea to remove cl_cmdbackup like on Source engine, so players don't mess with it.

@AnAkIn1 I'm sure. For tests I use a clean (no plugins, no metamod, no nothing) server downloaded via SteamCMD.

Server needs to be updated again, been seeing this on a server I play regularly on.

Tried my local linux steamcmd hlds and saw it also, went away after I updated (app_update 90 validate) my local hlds though.

Server version should also be version 5971. (not sure if server 5971 is a beta though, I probably opted in to the beta on my local hlds)

edit: yeah, server 5971 is a beta opt in, maybe they'll push all the beta changes to release today.

It happens on all servers.

[alfred-valve]

I increased the max pending move commands you could send with the last beta updates, servers will also need to update to allow the same number (that beta update will be out today). Running on a listen server should work so I will work out what is going wrong with that.

@alfred-valve : Is there any point to change cl_cmdbackup value?

[ghost]

@alfred-valve Everything is fine on listenserver. Is it possible to write some back-compatibility code? I don't think that server admins will know about SteamCMD and update their servers in a short period of time. I get kick on all servers when a map is changing, old ones, new ones, it doesn't matter. Or force everyone to update their servers: https://github.com/ValveSoftware/halflife/issues/665#issuecomment-14297981
