Subject RE: Getting a heap dump on OOME from Tomcat-as-a-service on Windows?

When you view service properties, does it run under system account or did
you give it a specific account to run under. You might try to use your
account under 'Log On' tab and see if you get results.  

(Assume this works when you run this from commandline ).

Gave Everyone full control of the C:\crap directory.  Configured Tomcat
through the service monitor to also append -XX:HeapDumpPath=C:\crap to the
list of Java options.  Started and stopped the service.  Ran the build.
Heap dumped, but no file was produced.  Searched the entire computer for
.hprof files; no results.

Anything else before giving up?

Best,
Laird
