Restarting httpd with mod_cluster results in a break in session affinity with JBoss

Solution Verified - Updated -

Issue

  • We use an httpd/mod_cluster loadbalancer set up. When we restart httpd, sometimes we see a break in stickiness for some sessions soon after.
  • We don't have replicated sessions so that break in stickiness results in a new session when the request goes to a different JBoss instance.

Environment

  • JBoss Enterprise Application Platform (EAP)
  • JBoss Enterprise Web Server (EWS)
  • Apache httpd
  • mod_cluster
