It's an internet issue. If the server's upload/download can't keep up with all the info it needs to handle, I think it starts dropping stuff and never picks them back up again. You can get this error with any map, as long as your server's internet connection sucks. It has nothing to do with CPU. I would like it was so simple, but it isn't. I've already tested this probability by using client on the same computer through localhost: same issue (but this wasn't an issue from the begining as the server have a good internet connection - long monitoring and good statistics: no packet losses). As i've wrote, this happening only on Bedford Falls map (regardless of any conditions: fresh clean installation + Bedford Falls, firewall, direct ip, vpn). Other maps, including Dreadwood aren't affected at all.
