Re: [jruby-user] Out of memory problem with JRuby-Complete

Hi,

so now your application is not portable: it's Windows specific, because of
win32ole. Worse: you need the software MS word to be installed. This
reduces the number of people who might help you out in this community.

If you still wish to keep this way forward, please have a look at the
memory availabe on your machine, and how pagefile.sys is configured on your
windows OS. I suggest to contact the win32ole maintainers.

Now there's real hope: make your application portable on JVM. Try Apache
POI and stay in the java world.

You might still need to increase your heap, and if you're using jvm 7 or 8
(please use JDK not JRE), you could use java control monitor to have a look
at your jruby memory allocation.

Good luck!
