To Reproduce

I caught this while running the following on a GCE worker (with master 9c41c48 build):

roachprod create -n3 local
roachprod put local ./cockroach
roachprod start --env "COCKROACH_ROCKSDB_CONCURRENCY=5" --env "COCKROACH_LOG_SST_INFO_TICKS_INTERVAL=6" local

workload run kv --init --histograms=perf/stats.json --concurrency=8196 --splits=100 --duration=30m0s --read-percent=0 --min-block-bytes=1024 --max-block-bytes=1024 --tolerate-errors=true 'postgres://root@127.0.0.1:26257?sslmode=disable'
