One of the many affected scenarios is perflab_eap-7x-failover-http-session-shutdown-dist-sync-shared-sessions: it is a 4 nodes (running with the standalone-ha.xml configuration) fail-over scenario where the deployed EAR contains two WAR sharing http sessions:
clusterbench-ee7-shared-sessions.ear/META-INF/jboss-all.xml:
<jboss umlns="urn:jboss:1.0">
<shared-session-config xmlns="urn:jboss:shared-session-config:1.0">
<session-config>
<cookie-config>
<path>/</path>
</cookie-config>
</session-config>
</shared-session-config>
</jboss>
During server shut-down the EAR is stopped and we observe the following error:

Also other scenarios like perflab_eap-7x-failover-http-session-shutdown-dist-sync-nb-state-transfer and perflab_eap-7x-failover-remote-jdg-session-shutdown-invalidation-sync-hotrod exhibits the same error: I assume it does not depend on the shared sessions configuration mentioned above;
Find attached:
- the complete server log (perf18-consoleText.txt)
- the EAR used for the shared-sessions scenario (clusterbench-ee7-shared-sessions.ear)
- the EAR used for the perflab_eap-7x-failover-http-session-shutdown-dist-sync-nb-state-transfer scenario (clusterbench-ee7.ear)
