Possibly a bug in your testnet code? Are you running stock software or your own code? ---

Dear cosmos forum: got the attached error similar to the one in this thread. Running gaiad v0.34.10. Any suggestions to fix? Thanks! ![Screenshot from 2019-12-05 17-52-08](https://canada1.discourse-cdn.com/flex031/uploads/cosmos1/original/1X/64a2853680855f4f65cff141e67c9af5d7b7fdd8.png) ---

Can you give more detail about it? What did you do? ---

Node was synced until block height 2,808,192. It regularly showed errors from the peers (e.g., too many open files, dial tcp timeout, connection failed at recvRoutine) but most of the console output was executed block/committed state. Edit: updated with error when I try to restart the node ![Screenshot from 2019-12-06 09-44-31](https://canada1.discourse-cdn.com/flex031/uploads/cosmos1/original/1X/32c91466cea86a148eaaca973ace44140b81031e.png) ---

Maybe it is the data error. You can try following command. @Scott cd ~/.gaiad/data rm -rf !(priv\_validator\_state.json) vim priv\_validator\_state.json 1、Remaing these fileds, and delete others “height”: “0”, “round”: “0”, “step”: 0 2、Start the gaia
