what i would do in your case is edit the bottom part of your config.cfg file
i'm assuming you're running 2 dedicated servers
and on each dedicated server is each running a copy of MAM.
this line
[statistics_mysql]
host = "127.0.0.1"
user = ""
password = ""
database = "mamstats"
prefix = "mam01_"
change the prefix to something else.
tdm01
or
gungame
and it should log the stats files seperately.
