Under Calibre 32-bit, the program can't use more than 2GB in total. I don't know what happens if there isn't enough memory to complete a conversion. It might be aborted; Calibre could also possibly crash.
Yes, I have a couple of Delphi collections that I'm unable to convert on my current laptop with 4GB RAM. I'm planning to replace my laptop by one with 16GB RAM shortly, which should allow me to convert them using 64-bit Calibre.
