Geth Network Halted Due to Teku Keystore Lock Error

[gunanshuCN]

Hi, I’ve been running a Geth network successfully for 7 days, but yesterday it suddenly stopped working. On checking the logs, I found the following error in the consensus layer container, which seems to have caused the network to halt:

2024-11-05 09:46:34.274 FATAL - Failed to load keystore, error Keystore file /validator-keys/teku-keys/0x96947de9e6068c22a7716656a2755a9551b0b66c2d1a741bf84a088fe1e840e992dc39861bf8ba3e8d5b6d21e8f57e64.json.lock already in use.

Here's the YAML configuration used for the network:
