**Status:** review
**Milestone:** 5.23.07
**Created:** Thu Apr 06, 2023 04:10 AM UTC by Thien Minh Huynh
**Last Updated:** Thu Apr 06, 2023 09:32 AM UTC
**Owner:** Thien Minh Huynh
Reproduce:
- Increase logMaxPendingWriteRequests to increase the resilience of log service
- Make NFS hang
- Make out of sync on standby
- Make NFS normal
- Trigger switch-over
- expect osaflogd on stanby coredump when got peer checkpoint
