Account sequence mismatch while publishing block

[tzdybal]

Summary of Bug

Yesterday I found following error in the logs in Optimint:

7:18PM ERR error while publishing block error="DA layer submission failed: failed to submit tx: code 32: account sequence mismatch, expected 14615, got 14614: incorrect account sequence" module=BlockManager

Version

@evan-forbes please confirm which version of DALC was used on your server.

Steps to Reproduce

I'm not able to reproduce. This error occurred when my server was severely overloaded (but TBH I don't see how this could affect execution).

Consider following scenario:

• DALC calls QueryAccount
• Celestia block is finalized, next block is pending
• DALC submits invalid Tx

Is this a possible source of the error found in logs?

it was using the latest commit on the evan/sample branch, I'll look into this error and finish up that dalc PR by the end of the week
