Ciao, aleunix.

See http://imagemagick.sourceforge.net/http/www/FAQ.html#C9 on memory allocation formulae.

Also, in the end, the png isn't made, remain 0 byte.
Do you get any error messages? A little internet search told me that a frequent complaint is getting memory allocation failures. And the same search informed me that you can add -debug all to your convert command to obtain more information.

I don't use ImageMagick ... but from your description and from that search I will take a guess that you need to review your ulimit (bourne shell based shells) or limit (c-shell based shells) values, and make appropriate adjustments in login.conf(5).
