OutOfMemoryError on Websphere, not in WSAD test environment

We're creating some on the fly pdf files in WebSphere Application Developer
(WSAD 4.0.3) and testing it in its internal WebSphere Test Environment.
Everything works just fine, and PDF files are created and displayed. BTW,
its nothing too complicated, usualy single page with single table in it.

However, on our real WebSphere Application Server v4.0.4, I'm getting the
following error:

Does it really means that WAS needs more memory or it is maybe some
recursion gone mad :-) or maybe broken font file (we're using TTF's).
Development is on windows machines and deployment on AIX.

Thanks,

Might be, since I got the following error, also OutOfMemoryError:

Thanks for the tips, I'll let you know what's going on.

Check the memory settings of your JVM first. The Unix version
may have a smaller default, or things just take up more space
there (caching, threadss, whatever), or you are even using a
completely different JVM version.
Consult your friendly WebSphere manual about where to set
addidional JVM flags.

I'm using TTF files from Windows 2000, namelly Arial (all combinations of
slants and weights) and Lucida. Everything is fine on Windows, but on AIX
the error mentioned before appears.

FOP  is 0.20.3.

I'll try different fonts and FOP versions and let you know what happens.

Thanks.

That allocates byte array for reading font file. Which fonts are you using?
