Re: Tomcat connections not closing.
Mike-
I would strongly suggest use of Version Control for archiving your
configuration files
server.xml/web.xml and context.xml, catalina.policy, logging.properties,
workers.properties, tomcat-users.xml
In the case of axis you want to archive
axis2.xml/services.xml/modules.xml/services
In the case of struts you want to archive struts-default.xml
struts-portlet-default.xml
In this way you determine at least the version of the configurations (and
hopefully date-time as well as Login)

Well, yes and no.
Yes, the problem has abated, and possibly been eliminated. However, we
have no idea what change fixed it. We changed nothing in tomcat, but
some changes were made at the network and in the application itself
(regularly scheduled updates). None of the changes were intended to fix
the problem, but it went away anyway.
I don't like it, since I assume the problem could come back at any time.
I still think Tomcat should be able to protect itself from this kind of
behavior, but I haven't had good luck yet with the suggested parameter
tweaks. At this point I'm not continuing to look into it, but just
keeping watch over it...

Mike,
Have you been able to make any progress with this? I'm very interested
in the outcome as we experience the same problem.

Hi Martin,
We are using version control. That isn't really the issue. The
problem is too much data, not too little.
