IT26795: DSMRECALLD CAN COREDUMP WHEN HOST SYSTEM IS REBOOTED

APAR status

• Closed as program error.

Error description

• When a host system is shutdown, where Spectrum Protect for Space
  Management for UNIX runs, there is a possibility that
  dsmrecalld daemon can crash with a core dump.
  The daemon will start ok again, and no consequence is seen.
  
  
  
  Running getcoreinfo utility on Linux shows a stack similar to:
