Shutdown log - deallocating instances
Hi,
We have been running a couple of web application on a tomcat 5.5 server.
The OS is Linux based FC4.
Off late, I have been noticing that during a shutdown of the server I
see a message
"Waiting for xx instance(s) to be deallocated"
The xx number varies (today it was 154). Can someone tell me what this
means and if I should worry about this at all? So far the server behaves
well and we have not come across any hanging type situations. But we are
slowly moving into full production mode and I want to make sure this
will not cause a problem down the line...
Thanks for the help.
Here is the log from the last shutdown...

Thanks Charles.
Is there any other way to know which servlets are casuing this issue??
So, i I dont fix this problem, is there a potential of a break down in
the near future?
Any one else encounter this problem? What are the typical causes?

This message is logged up to three times for each servlet that has a
non-zero allocation count, waiting for it to decrement to zero. After
the third message, the ServletWrapper code just goes on and calls the
servlet's destroy() method. Looks like you have two servlets that
aren't always terminating properly. Unfortunately, the log message
provides no information about which servlets those might be. The code
in question is in the unload() method of
container/catalina/src/share/org/apache/catalina/core/StandardWrapper.ja
va
around line 1300 in 5.5.20 if you want to change it to display more
information.
