DB2 FOR LUW / DB2FORLUW / A50 - DB2

Problem description

pureScale cluster and the lock notification to reclaim is lost 
then an application hang may occur and possibly an entire 
database hang depending on the current locks held by the 
application in a hang state. 
 
A missing lock notification can be triggered during cable pull 
when an adapter goes down, 
or a lock notification timeout where the following error is 
logged:
