- Title
- qa: timeout in StopHTTPServer()
- Description
- Ran into a CI timeout in *feature_assumeutxo.py* on Windows: https://github.com/hodlinator/bitcoin/actions/runs/13371466603/job/37340702068#step:12:123
In the combined log we see the following, "Restarting node to stop at height" is [referring to node 1](https://github.com/bitcoin/bitcoin/blob/790c509a4796ec47be2275d86b35370ff25a599a/test/functional/feature_assumeutxo.py#L586)):

test_framework.authproxy.JSONRPCException: 'stop' RPC took longer than 2400.000000 seconds. Consider using larger timeout for calls that take longer to return. (-344)
```
Note how it takes:
- ~40 seconds to go from receiving stop-RPC to "enabling extra block-relay-only peers"
- Additional *14 minutes* to reach "Flushed 0 addresses to peers.dat"
- Additional *15 minutes* for the second one
- Additional *10 minutes* until we reach the JSONRPC error/timeout.
It would be good to have log output describing what the node is doing, it obviously started shutting down, and is maybe still flushing some state to disk?
Also, I wonder if bitcoind might have terminated the TCP/HTTP connection before responding to the `stop`-RPC (maybe `gettxout`-RPC being called right before it is a factor)?
Included in the log, but seems unrelated as it's another node:
```
node0 stderr Error: A fatal internal error occurred, see debug.log for details: Assumeutxo data not found for the given blockhash '7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a'.
