$cacheDBs{$db}{mxs} is a hash reference. If you want to print its keys and values, do so: 
for my $key (keys %cacheDBs) {
    my $mxs = join ':', map "$_ $cacheDBs{$db}{mxs}{$_}", keys %{ $cac
+heDBs{$db}{mxs} };
    print "\n/opt/freeware/bin/gmetric -n $db -T $db -g $Ggroup -t dou
+ble -u MaxSize -v $mxs -d 45)\n";
}

Untested (the code was not runnable to demonstrate the issue).
