Abstract

LIC-OTHER-SRCB6005121-INCORROUT STACK RECURSION PROCESSING
UNEXPECTED TAPE LIBRARY CONFIGURATION

Error Description

If the saved configuration information for a tape library is    
unexpected, the device driver will attempt to log an error. In  
some cases, this may cause an incorrect call back that causes  
the partition to terminate.
