Several configuration settings in Bitcoin Core can impact how stale blocks are handled and how long they are retained. Here are some key settings:

1. **`dbcache`**: This setting controls the amount of memory (in megabytes) allocated for database caching. Increasing this value can help the node handle more data in memory, potentially allowing it to retain stale blocks longer.
```
dbcache=1024
```

2. **`maxmempool`**: This setting determines the maximum size (in megabytes) of the memory pool for unconfirmed transactions. While not directly related to stale blocks, it can impact overall memory usage.
```
maxmempool=300
```

3. **`maxorphantx`**: This setting specifies the maximum number of orphan transactions (transactions whose parent transactions are unknown) that the node will keep in memory. Again, not directly related to stale blocks, but it affects memory usage.
```
maxorphantx=100
```

4. **`blockreconstructionextratxn`**: This parameter specifies the number of extra transactions to keep in memory for block reconstruction. This can indirectly affect how much memory is available for other purposes, including stale blocks.
```
blockreconstructionextratxn=100
```

5. **`prune`**: If you are running a pruned node, this setting controls the amount of disk space used for storing block data. While pruning primarily affects disk storage, it can also influence how long blocks are kept in memory.
```
prune=550
```

6. **`maxconnections`**: This setting determines the maximum number of inbound and outbound connections. More connections can lead to higher memory usage, which might impact the retention of stale blocks.
```
maxconnections=125
```

To adjust these settings, you can add them to your `bitcoin.conf` file, which is typically located in the Bitcoin data directory. For example:
```
dbcache=2048
maxmempool=300
maxorphantx=100
blockreconstructionextratxn=150
prune=550
maxconnections=125
```

Keep in mind that these settings should be adjusted based on your specific hardware capabilities and performance requirements. Given that you're using a Raspberry Pi 5 with 16 GB of RAM, you have some flexibility to increase memory-related settings, but always monitor the node's performance to ensure it operates smoothly.
