[mapguide-users] MG Error Out of memory, bad allocation

One of the options may be to merge together files.
I have an image, 32000x16000 tiled RGB tiff, 1.7GB in size which is
served like a lightning by an old computer, not even designed to be a
server, with 1.5 GB of RAM.
Software configuration - same as yours.
By merging rasters you can reduce the number of files almost 60 times,
which means that you will have 15-20 files, roughly.
Of course, you know better, if your project allows this, but in general,
MGOS seems to handle easier a small number of big files, rather than a
big number of small files.
