I used the Java options provided by IBM. Since Tomcat will successfully start
using the startup batch files, I assume that these settings are fine. I've
tried playing with the settings and cannot get it to work either. I seems like
it's some sort of weird Windows thing.
I have successfully configured these services before with prior version of
IBM's CLM. The difference in those previous versions was that Tomcat came
bundled with t heir product. For this latest IBM version, Tomcat was not
bundled and they provided instructions for downloading it from Apache and
instructions for where to install it.
I have escalated the issue with IBM's support and since they are providing the
JVM, it is probably their issue but wanted to put it out to the larger
community to see if anyone has ever had this issue before. A user on the user
forums said that the memory error in the Tomcat log file is a red herring and
that it is giving that memory allocation error because the JVM didn't actually
start. So, the issue seems more connected to the error in the Windows Event
viewer ("cannot open file").

Note that, depending upon how you set the CATALINA_HOME environment variable,
rebooting will lose this value. I'm not sure the reboot was necessary.

That's a BIG buffer. Do you need 1G NIO buffers? A web-based video-editing
application?

What is -Xmn? It's probably not a problem, but I thought I'd point-out
something that looks weird.

Is it possible that you have the 32-bit service runner? That would cause the
JVM to run in 32-bit mode when you launch as a service. Selecting the JVM DLL
directly should definitely select the right JVM (and
architecture!) but I'm not an expert on Windows and Windows Services.
