I've suspected that it has to do with the # of files the JAVA session has to the hard drive. It seems that it really started getting bad when multiple sources was introduced, but when I allow a bunch of simultaneous downloads it starts dropping files.

It seems like it's more of a problem downloading big files, so I've thought that maybe every connection to that 700MB file reserves 700MB somehow, and then it has problems with disk space, but I haven't really figured out how to verify this theory.
