Looking at the above log, I see that (apparently) Tomcat receives a succession of shutdown

commands, at more or less 1 second interval.
How do you do that ?

(I am asking because as far as I understand what is happening, each invocation of a 
"shutdown.bat" starts a separate instance of a Java JVM, and at least a part of Tomcat 
within it.  Isn't the fact of starting those multiple JVMs in such a short time, on a 
Windows laptop, by itself a possible cause of the issue ?)
