APAR status

  • Closed as program error.

Error description

  • In 12.10, the shared lock implementation was changed. Our
hpux-ia64 code uses spin-locks instead of atomic operations to
set shared locks. This creates the possibility for excessive
spin-lock contention in parallel operations like table loads.
