Describe the bug
No matter the Init.MemoryHint option, Nethermind always slowly but steadily fills up the swap on my system. The machine has 32 GB of memory, and vm.swappiness set to 5. Currently, 3.11/4 GiB of swap is in use, while only 17.1/31.2 GiB of memory is being used.
Only other programs running are Nimbus and mev-boost, both of which behave nicely.
To Reproduce
Happens always.
Expected behavior
Nethermind uses available memory instead of swapping onto the disk.
Increasing init.MemoryHint reduces swap usage. It has no effect: only increases memory usage.
Reducing init.MemoryHint reduces swap usage. It has no effect: only decreases memory usage.
Screenshots Grafana dashboard with evolution of memory usage over the last four days. Initial drop in swap usage is due to a restart of Nethermind.
