Thank you (Charles/Ranier) for your help. I had mt'd the option name, but found that I just had it set too high. It wasn't taking 256m and would start if I set it lower. I understand '-D' now as well.
Now to see if we have some bad leaks or we just needed more breathing room.

In Tomcat6w.exe, I set one java_opt to include -XX:MaxPermGen=128m, MaxPermGen is wrong, MaxPermSize is right.

Since -D... doesn't change memory settings, you will still run with 64MB max.
