Hi,
Is there any other error messages other than those map limit error messages if you scroll up/down your mapserver window?
Usually the error message would be like "[ERROR] File Not Found : <dir> " or "Failed to connect to ..." or something like those.
Source file that has something to do with the map limit is in src/common/mmo.h with this entry:
 
The easiest and quickest fix is re-download the whole new server files; and keep your configuration files and database from your old server.

Hi,
Try to check your sql-files/upgrades/ 
and see these files: (contain mail_attachment)
upgrade_20160814.sql
upgrade_20170620.sql
upgrade_20171001.sql
Update the script if necessary.
And make sure your charserv has rights to access to your database via firewall settings.
It is also worth checking if your main.sql script is fully integrated with your char.cpp.
Lastly, ensure your inter_athena.conf contains these: (Never edit these)
