Database or Era files corrupt on Mainnet
**Describe the bug**
Recently we've been seeing errors like this on Mainnet nodes, in this case `libp2p-01` on `linux-07.ih-eu-mda1.nimbus.mainnet`:
```json
{"lvl":"FAT","ts":"2024-03-11 11:20:37.394+00:00","msg":"Era summaries don't lead up to backfill, database or era files corrupt?","bid":"c78a68b6:8518954"}
```
A previous instance of this happening was with `unstable-02` on `linux-03.ih-eu-mda1.nimbus.mainnet`:
```json
{"lvl":"FAT","ts":"2024-03-08 08:11:18.637+00:00","msg":"Era summaries don't lead up to backfill, database or era files corrupt?","bid":"bd80c153:8503305"}
```
Which was purged and allowed to resync. The `libp2p-01` was left in a broken state for debugging.

**Additional context**
The `unstable-02` was running `v24.2.2-3b4b1c-stateofus` when issue was discovered(probably).
The `libp2p-02` was running `v24.2.2-1fef38-stateofus` when issue was discovered.

No issues were identified by `verifyEra` command.
