Adding multiple servers on LB creates the issue

Networking And Security
#1

I have tomcat service with 4 servers behind the LB. All of sudden the service started failing one by one and now I have only one server behind the LB serving my production requests (Like activating an user to a portal). If I add the second server, tomcat service looks fine but the user activation started failing.

Dependency services are running fine and connectivity check also looks good. Tried adding all other 3 servers one by one behind the LB but still the user activation is failing. But the user activation is happening when we have one server behind the LB.

What could be the issue?

Hi Ramesh,

As you confirmed, tomcat service and lb health status is fine with 4 servers behind lb. Seems, Issue is related to application session or load balancer sticky session.
