after an application is removed from a WebSphere Liberty

PROBLEM SUMMARY

USERS AFFECTED:
 All users of IBM WebSphere Application
Server using Intelligent Management in the
WebSphere plug-in

PROBLEM DESCRIPTION:
Intelligement Management enabled
WebSphere plug-in stops routing after
an application is removed and re-added
to a cluster

RECOMMENDATION:
None

The routing table maintained by the Intelligement Management
in the WebSphere plug-in goes out of sync after
an application is removed and re-added to a cluster, which
causes it to stop routing requests to the application.

PROBLEM CONCLUSION:                                             
Intelligent Management in the WebSphere plug-in was changed to  
fix the problem.
