hi,
The defaulting to 8MB is interesting and is crazy low; even more interesting that the setting appears to be buried somewhere(as an aside mariadb also defaults to 128mb so not a mariadb issue). After we get the settings hammered out, we can then place them on the wiki (and refer from the install manuals) and will use them when release the next xampp package (although this will likely be using a more modern version such as 7.0 which will likely not have the 8MB default or at least one would hope it wouldn’t).
