APAR status

  • Closed as program error.

Error description

  • If background deletion queue is full, then a full scan
deletion is required to free the inodes marked for
deletion. In some cases, the full scan deletion fails to
run and the inodes don't get free until the next
invocation of full scan deletion or node recovery.
