Two signer nodes lost their peers
Two signer nodes lost their peers on 28 October and fell behind while the others kept sealing. Both were reconnected on 7 November; all six seal in turn again.
- Impact
- Two of six signers not sealing for about ten days; no chain halt observed
- Root cause
- Peer discovery through the bootnode returned no peers, and no static peers were configured
- Fixes
- Static peers on every signer; self-healing watchdog every 60 s; automatic recovery of hung machines; daily snapshots; alerts for fewer than five active signers
