    Hi Alexander,

    thanks for responding,
    i tried these settings but ran into a memory exception. I managed to
    get the complete file converted to pdf but it took more than 12 hours
    and it turned out to be 821 pages. I used the settings -Xms16M -Xmx1024M
    validation is off, but i only have 512 MB in my machine. I am using windows
    2000 server and sun jdk 1.4.1_01.

    I am now trying -Xms128M -Xmx800M, with -Xmx600M i ran into a memory
    exception as well. Would buying extra memory solve the problem or would that
    only reduce the conversion time from 12 to 11 hours or so ?

    kind regards,

            Jack Broeren (Ambrac)
