Avalanchego with subnet-evm stopped validating suddenly

[ongrid]

Describe the bug Avalanchego v1.7.18 with subnet-evm v0.2.9 suddenly stoped validation or/and distribution of blocks after uptime of 1 week. Timeframe when it happened is 08-31|03:49 (see logs attached). Process didn't restart, peerings were steady, no infrastructure events were noticed at that time. Avalanchego process restart restored its proper operation.

Without anything more to go on - I don't think there is really much to do here. If something like this happens again it would probably be good to set the log level to debug to try to see what is actually going on under the hood (requires enabling the admin api).

If there is any replication here feel free to re-open this.
