Chitubox seems to use an extreme amount of memory. I opened a 12MB file, sliced it, saved it, added supports, hollowed it, resliced it, added a few more supports and I noticed that ChiTuBox 64 had used *9.2GB* of memory out of the 32GB of memory I have. I noticed that each time the hollowing action took place, the progress bar for "hollowing" appeared many more times than the actual number of models I had on the platform. Eventually slicing and the hollowing action took around 10 minutes to complete instead of the 15 seconds it took when I first opened the file.
So either there is a significant memory leak or the application is reserving ridiculous amounts of memory and not releasing it or garbagecollecting it.
