bitcoind rpc command timeout

Question

I'm running bitcoind v0.17 after booting it and running it for a little while, it eventually timeouts ALL rpc command requests. If I use the CLI as well, it also times out.

This is what happens:

I checked the debug.log and there's nothing that I can see that explains what's happening. Tail of debug log:

Any ideas as to how I can go about debugging this?
