Issue/Introduction

'wp.events.RoutingSessionListener: HTTP session is about to be destroyed' logged in Spotfire server logs.

Environment

All Supported OS

Resolution

  • The 'RoutingSessionListener' mentioned in log snippet performs certain cleanup/shutdown actions that needs to take place when/before HTTP session is destroyed. A session may either be destroyed due to the user logging out, or due to an idle timeout. 
  • Spotfire server's access logs (<Spotfire Server Install>\tomcat\logs\access.log) should show if the users are actually logging out. You can refer attached access.log file for actual user(nmomin@apacanalytics.lab) logout entry.  If this is not the case and if the number of expiring sessions is higher than expected then one need to start by looking at load balanacers or such in front of the Spotfire server, perhaps session cookies get lost or perhaps the load balancer doesn't properly maintain session affinity so that requests within the same session are routed to different servers (resulting in new sessions being created).
