Abstract

OSP-OTHER-WAIT STRCAD MAY HANG DUE TO AN INTERNAL LOCK
CONDITION.

Error Description

When performing STRCAD a hang may occur due to an internal lock
condition.                                                      
                                                               
Due to damage on internal QFPATMAP index, it can cause an issue
where locks are not being released properly and allowing proper
handling of the index by admin domain.                          
                                                               
Code is being enhanced to handle appropriately and prevent.    
                                                               
Work Around: With Cluster Active on all nodes in the cluster    
and all related jobs, admin domain can be in an Inactive        
status. The node where the damaged index resides can be removed
from the admin domain, then admin domain can be started to      
ensure all other nodes get updated and show consistent MREs.    
The problem node can then be added back into the admin domain.
