Subject RE: tomcat on windows 2012 weirdness
Date Thu, 11 Dec 2014 21:00:30 GMT
I noticed the ridiculous number of session issue on one of my servers, but it wasn't Windows
2012, but 2008 R2.  Don't think the windows version has anything to do with it, but something
about the Tomcat version.
Looking at the manager, I had a couple hundred really old sessions, several hours expired,
that were still showing up in the list.  When I click on the "expire" button, they all went
Noticed this when I was starting the upgrade to the latest Tomcat 7 release, and haven't checked
back to see if it is still an issue since the upgrade.  If I get a little time later today,
I'll recheck.
