Many possible reasons. More investigation is required. Is your web
application cluster enabled? What do the logs tell you is happening with
the cluster?

Frequently.

org.apache.catalina.session.level = FINE
org.apache.catalina.tribes.level = FINE

is probably overkill but you can narrow it down once you figure out what
is useful (or not) for your situation.

Fwd: tomcat 8.0 session_id resets in AWS

2016-06-29 Thread Gibu George
Hi All,

I'm trying to get tomcat to work in a cluster with sessions being persisted
in mysql, in AWS. I have setup two tomcat servers in the clusters using "
org.apache.catalina.tribes.membership.StaticMember".

The problem that I am facing is that when a request that containing
session_id created by tomcat instance1 is send to tomcat instance2, tomcat
instance2 fails to validate the session_id ( created by instance1 ) and
send a new session_id, created by instance2 in the response.

Why is this happening? Has anyone face such an issue ?

my tomcat is front ended by nginx

Part 2: How do I enable logging for session management in tomcat? What do i
need to add in logging.properties file?
