Key mcserv.exe /debug — run the server in a debug mode
The key is for debugging MyChat Server. In this mode, the server keeps detailed text logs in files located in the folder C:\ProgramData\MyChat Server\logs\ sorted by years, months, and days.
A server's performance might be lower in this mode. In some cases, protocol files can be huge (dozens, hundreds of megabytes of text).
By default, this work mode is disabled.
