Hi Team,
I encountered a bug while applying incremental backup today. Please help me to understand this issue.
It was routine activity and i never faced this issue before. i am using percona-xtrabackup 2.3.10-1 and percona-server 5.6.40-84.0-1.
Bug details as below…

This could be because you hit a bug or data is corrupted.
This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
