This is also about our clustered Tomcat 8 application running on Google
Cloud.
The Report sub-cluster runs BIRT. And the default landing page is the
Eclipse BIRT viewer default landing page, the one that shows an Eclipse
logo, and says "BIRT viewer has been installed."
I've got a health-check on that sub-cluster, that polls the default
landing page of ROOT periodically. Up until a few days ago, it was
polling it every 5 seconds; earlier this week, I cut it down to every 5
minutes (the maximum); now I've got it at every 30 seconds.
If I open the Manager context, I find that it shows (currently) around
180 sessions for the ROOT context. When it was going every 5 minutes, it
was showing 18 sessions; when it was going every 5 seconds, it was up to
over a thousand.
The other two sub-clusters don't have any dangling sessions from their
health-checks; why would this one?
I'd like the sessions from all this health-check polling to expire a bit
more quickly; can anybody here suggest a way to accomplish that?
