Possible memory leak when running witch --gcmode full

[1aBcD1234aBcD1]

System information

Geth version: scroll-v5.5.0 OS & Version: Ubuntu with docker version 25.0.2, build 29cf629

Expected behaviour

Actual behaviour

I have been trying to setup a full node instead and an archive node. When using the --gcmode full, geth service crashes since it consume all the RAM of the server.

Seems memory leak is in function func (l *ZktrieDatabase) Put(k, v []byte) error at trie/zk_trie_database.go line 39.

Steps to reproduce the behaviour

• Build docker image
• Run it as follows:

  geth  --datadir "gethdatadir" --http --gcmode full  --http.addr "0.0.0.0" --http.port 8545 --http.api "eth,net,web3,debug,scroll" --l1.endpoint "eth_rpc_url" --rollup.verify --http.vhosts "*" --maxpeers 100 --http.addr "0.0.0.0" --http.port 8545 --http.api eth,web3,net,debug,trace,txpool,admin --ws --ws.port 8546

Backtrace

You can check the heap and allocs from the following files heap.txt allocs.txt

Thank you for reporting this. Currently we only support --gcmode archive and full mode is known to not work, but we will work on adding pruning in the near future.
