Abstract

LIC-OTHER-SRCB6005121-UNPRED SYSTEM HEAP LEAK DURING TAPE
INITIALIZATION

Error Description

If a tape drive is looking for an owning library, while either  
the system is being IPLed or the controlling IOA is being      
IPLed, System Heap can be leaked. If this happens enough, the  
system can run out of System Heap control segments, leading to  
a crash.
