![]() APAR status Closed as program error. Error description Problem: After PTF 3 was applied, the nanny.trace file contained multiple instaces of the message "NMSV0602E: Naming Service unavailable. A communications error occurred." and when any one node is down, unable to successfully regen the plug-in. PQ61462 did not affect the situation. .

These improvements prevent the entire plugin regen procedure from failing completely and provide more graceful error handling for the user.Temporary fix Comments
