The "tomcat6-stdout.2014-07-21.log" file is just a file that Apache
Commons Daemon procrun (the service launcher used here) uses to catch
the standard output stream (System.out) of the started process.  It
can be configured, but it won't help you if you want a separate name
for each dump file.

To catch dumps into separate files you can use "jstack" tool from
Oracle Java SDK.
