On-disk DB structure large on initial sync until restart

[yorickdowne]

System information

Geth version: 1.10.20
OS & Version: Linux Ubuntu 22.04

Expected behaviour

After snap sync of mainnet, expected DB size around 560-570 GiB

Actual behaviour

After snap sync of mainnet, on-disk DB size is around 815 GiB

Restart Geth once, this reduces to around 780 GiB

Restart Geth a second time, this reduces to around 565 GiB

A third restart does not change on-disk size

I am unsure whether this is a bug or a feature. It certainly is unexpected, and not how Geth behaved in previous versions.

Have a same issue.
For me geth created many files, which removed after restart geth. Almost 200-300 Gb were removed after each restart.

Geth version v1.10.20
Geth command:
geth --cache "2048" --datadir "/data/var/lib/ethereum_wallet/" --ipcpath="/data/tmp/sock_geth.ipc" --http.api eth,web3,personal --http --http.addr "0.0.0.0" --http.port "8545" --syncmode "full" --ws --ws.addr "0.0.0.0" --ws.api eth,net,web3 --txpool.globalqueue 5000 --snapshot=false &>> /data/eth/var/log/ethereum.log

This was a bug in leveldb, we've downgraded to the previous good version in 1.10.21. Please update to that.
