I guess this makes it hard to reproduce with gdb attached or with more logging enabled?

Glancing at the code, I don't see how this could happen unless macOS `send` returned a value larger than the `len` passed in?

I've just started bitcoin mining a few months ago and I've chosen bitcoin core as the app to store my bitcoins, after 2 days of synchronizing with the network i've 18 weeks left and suddenly my bitcoin core application keeps freezing and not responding.

Mind moving this issue into the [GUI repo](https://github.com/bitcoin-core/gui) (closing this one and opening a new issue there)?

> my bitcoin core application keeps freezing and not responding.

If it keeps freezing after restarting, more details are welcome, for instance `debug.log` content (NOTE: make sure no private details will leaked).

Pretty sure it is just waiting for cs_main, which is needed in IBD. So this is expected, unless the GUI is made lock-free, for which there should already be an issue open?

Tested ACK: `FUZZ=addrman ./src/test/fuzz/fuzz`

Tried also with a few seeds added last month by @Xekyo:

Do we really need this?
```suggestion
```
Next line calling `AddrMan::GetAddr()` function passes `std::nullopt` as the network argument (meaning ALL_NETWORKS), so as `AddrMan::Size()` also interprets the same for the network argument and since even `ConsumesBool()` when returns false it would be `std::nullopt` (meaning ALL_NETWORKS), why to bother with this, just pass std::nullopt below when you call `AddrMan::Size()`, unless I'm missing something here.

As I explained my reasoning of this above in my first comment on the initialisation of the network variable:
```suggestion
(void)const_addr_man.Size(/*network=*/std::nullopt, in_new);
```

I was going to propose:
```suggestion
bool in_new{fuzzed_data_provider.ConsumeBool()};
```
``` ```
But then I checked also the definition of the`AddrMan::Size()`function consuming `in_new` as and argument and I see in the comments that it would interpret the 3 states:
```
/**
* Return size information about addrman.

* @param[in] net Select addresses only from specified network (nullopt = all)

Netstat tells me there's nothing listening on port 8332:

Detaching gdb and running `strace -f` on the process shows lots of activity:

As @willcl-ark, tried @theStack's method with no sucess, my libevent version is 2.1.7, I'll try to update it and retry again. Thanks.

@Crypt-iQ I did: Ctrl-C the waitforblockheight command before trying to stop bitcoind.
