Hi Trevor,

Thanks to your reply.

I added the two columns "Peak Memory Usage" and "Virtual Memory Size". For
this morning crash, the VM size was 800 MB. I know that 800 MB is a limit
for a 32 bits processes like ASP.NET Worker process ; maybe it is the same
for MapGuide but you are talking about 1.5 GB.

Anyway, I am continuing to investigate about ECW. I will try to merge some
files to have fewer but heavier files.
