My process just do a traceroute with it. It might be wrong that the issue is because of bpf. Would you please review the logs to find the cause? I've upload one more logs set user reported in FB ticket FB22371512, user disabled our process in this case. This is what I see from logs: 343 Server default 2026-07-24 15:10:34.104403 +0200 configd DHCP en0: supplying hostname 'DHRMAC-JK2093KWWG' 343 Server info 2026-07-24 15:10:34.105551 +0200 configd DHCP

No, I am not able to reproduce it, few customers reported it after deployed our app. I shared few system diagnose logs in the FB ticket.

Yes, our app was built on top of transparent proxy provider, we bypass DHCP from provider to make sure it communicates directly with its ultimate destination. However issue still been reported from customers when Transparent proxy extension running.

We saw this issue more with Content Filter and Transparent proxy network extension running on the device.

@DTS Engineer any update on this?

No sure how to attach full system log here since it is large. Please let me know how to share the full system log if you need

The crash is not on demand. The code I post is very independent, it just load and release DS, why CFRelease crash even null was checked and release DS right after copy?

Is there any other system API or any other way to get process static code by skipping endpoint security check?
