N-no, the problem is not with FOP, the problem is that I need to produce
documents really quickly for high-volume PS printers. My .NET app produces
the raw XML and uses Saxon to create the XLS and FOP to turn it into PS. The
problem is that if I fire up the Java VM for Saxon and then again for FOP,
document creation takes 7 seconds (way too slow.) If I turn those two
packages into .NET assemblies and avoid the start-up delays of the Java VM,
document creation times fall to 2 seconds as everything is in the same .NET
execution environment.
If you can tell me how to keep Saxon and FOP running whilst I push large
amounts of XML documents through them, I'd gladly give it a try.

Which is why I'm asking. It might be Saxon or something in IKVM that leaks.

Not that I'm aware of. The problem is complicated by it running as a web app
in IIS. It's the IIS worker process that grows until it get's too big and is
recycled.
Bye for now
