4. What is your TiDB version? (Required)

tidb 5.4.0

[glorv]

duplicated with #11940. @wavelet123 This is a known issue that is already fix in v5.4.2. Please either update your cluster to a version >= v5.4.2 or you can just workaround it by restarting the tikv within 795 days.

BTW, to repost an issue for tikv, better file an issue in the tikv repo.

Thanks glorv for the confirmation
