[ZendTo] PHP Fatal Error when downloading medium size encrypted files

[Jules Field]

Davide,

How much RAM has your ZendTo box got?
The crypto library does require quite a bit of RAM, so if you only have 
1 GB then I would at least add some more swap space. Obviously adding 
more RAM would be better (2GB or 4GB should be plenty), but possibly 
more costly.

Cheers,
Jules.
