### Current behaviour

The `bitcoind -dbcache=100 -par=4 -disablewallet -reindex-chainstate` command fails with OOM. First reported in https://github.com/bitcoin/bitcoin/issues/28718#issuecomment-1807197107.

### Expected behaviour

RAM usage does not exceed 0.9 GB.

### Steps to reproduce

100% reproducibility with Guix compiled binaries.
