Wallet error when checking balance

Tech Support
1

Hello everyone, my grin server is running with no log errors. My wallet and grin-miner are both running with no log errors. But when I check my wallet balance with this command:

./grin-wallet info

my grin-server.log will show several error lines like this:

ERROR grin_api::handlers::chain_api - Failure to get output for commitment 082d7a2f0e32086823c7df84ccb080fc914c9374d1ff4a320a252ed222e229687c with error Not found.

Wallet seems to open and show balances correctly, should I be concerned about this error showing in my logs?

Thanks for reporting. Would you be able to:

  1. try a grin-wallet scan and see if you get any errors
  2. save/archive your existing chain_data directory, remove it, resync from scratch, and see if you still get these errors in the log (and errors while scanning, if you had any)

I was using a fresh installed Debian OS, today I switched over to Ubuntu 18.04.3 LTS. Reinstalled everything. Still seeing the error in my server log when I check my wallet. Did as you suggested got this error in the grin-server.log (BTW - everything seems to run ok, gpu mining at 2.5 gps and two cpu servers each mining at around .200 gps. Check out the stratum server if you like no password needed: 185.148.146.41)

This is what I got when running the scan command:

Could this be a owner/group permissions problem? I noticed that grin-wallet & grin-miner are different from the rest.

I am solo mining and my grin server is running with a lot of log errors:

The last message was received when I checked my wallet balance with:
/grin-wallet info

Does this error appear in your grin-server.log when you check your balance? i.e. run ./grin-wallet info

Yes, message appears everytime when I check my balance.
