How to read the history?

I'm confused by the jepsen.log against etcd 3.5.15, produced by the README instructions:

lein run test --workload lock-set --nemesis pause --time-limit 120

More specifically, Line 893,894,932,955,996:

Where does the "requested lease not found" come from? Are there retries beyond the log?
