iOS 16.1.1 Crash :com.apple.network.connections EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000036

Unfortunately I can’t do much with a non-Apple crash report [1]. Can you post an Apple crash report for this? See Posting a Crash Report for instructions.

[1] There are a number of reasons for this but the primary one is that I don’t trust non-Apple crash reports, as explained in Implementing Your Own Crash Reporter.

here is apple crash report:

@eskimo

here is apple crash report:

I think it’s likely that this is a bug in Network framework itself. I recommend that you file a bug about this, including as much info as you have available. Ideally that’d include a sysdiagnose log but, seeing as you can’t reproduce the problem, just include any Apple crash reports you have.

Please post your bug number, just for the record.

I have also received reports from iOS16.1.0 and iOS16.1.1 users about the crash problem. besides, I encountered other Network framework error from iOS16.1.0 and iOS16.1.1 users。

hi @eskimo.

many days passed, do you have any workaround solution for the app side? It's hard for us if nothing to do with this crash

Thanks

bug number is：FB11830385

Looking through your recent posts it seems that you’re hitting multiple different crashes that are all look like memory management issues deep within Network framework. Given that variance, I’m going to take back my earlier comment:

I think it’s likely that this is a bug in Network framework itself.

When you see a bunch of problems that are similar but not exactly the same the most common cause is a memory management issue. Something in your process is corrupting memory in some way and that corruption manifests in crashes in different, unrelated parts of the process. My new advice is that you run the standard memory debugging tools against your process to see if they offer any useful debugging hints.

not all crashes are due to memory problems.For example
