use Man@log as a custom memory allocator by placing the Man@log.dll in the dll directory of the game and using command line -malloc=man@log
to take a snapshot of the memory run Man@lyzer.exe. It will create a binary mana.log file
Note: you can run Man@lyzer.exe at any time, it should be possible to run it even the game is frozen. The game will freeze for a while (10-30 seconds) during the dump.
two dumps should be created, standard (named mana.log) and detailed (named mana-detailed.log )
the mana.log will allow the developer to gather detailed statistics about game memory usage. Unless developer specifically requests for the detailed log, send the normal log, which is a lot smaller, but should contain enough information needed in most situations
