Server works fine(~1 month) since yesterday, i had message "MasterRequestRestart" in server console. I restarted my server and downloaded new files. When i tried to turn on my server, again received the "masterrequestrestart" msg
Now, after autoupdate i have msg "HLDS is up to date", few lines lower again masterrequestrestart command.
Any ideas?
