** [tickets:#2207] cpnd: osafckptnd core dump while handling error
section_hdr_update_fails**
**Status:** review
**Milestone:** 5.2.FC
**Created:** Thu Nov 24, 2016 09:45 AM UTC by Vo Minh Hoang
**Last Updated:** Thu Nov 24, 2016 09:45 AM UTC
**Owner:** Vo Minh Hoang
the steps to add a section is add_db_tree -> update_sec_hdr -> update_ckpt_hdr
so if an error occur cpsv should handle error in reverse order.
currently, section_hdr_update_fails, cpsv revert ckpt_hdr also that possibly
cause the problem
