Abhayam, and anyone else with a weird crash deep in CFNetwork, I’m happy to look at your crash report but please start a new thread for that. Make sure to:

Feel free to link back to this thread if you think there’s some specific detail that’s particularly relevant to your crash.

Beyond that, I’ve lock this thread because I don’t want it to become a collection point for every CFNetwork crash ever )-:

Hi Eskimo,


We are not able to get any clue from our debugging about this crashes in development. For better understanding about this crash , we have added the following line in all the NSOperation


[[NSThread currentThread] setName:[NSString stringWithFormat:@"Operation %d",operationID]];


but it is not displaying thread information in appstore crash logs. Do you know why thread name is not displaying in crash logs with the above code?


We are simulating the crash in adhoc build and able to see thread information in our development device.



Thanks,

Sakthivel

Please open a new thread for this question. This thread is already clogged with lots of different reports of CFNetwork problems, so I’d rather not pile more on to it.

I recommend the Core OS > Concurrency topic area.

I have been received almost 3000+ crashes in last 90 days.

This crash is only happening on iOS 11 (starting from 11.0 onwards)


Any solution to resolve this.
