Does free5GC support simultaneous multiple UE attach messages?

[free5GC]

Now free5GC has some architecture defect on multiple request in the same time and will be fixed in the next release.
We’re not sure if you reach this bug. If you can provide more information such as error log and pcap file, we can get more deeper for the error cause.

If CPE start second session establishment, 5gc looks hang

Hi, Sorry for that. This seems to be caused by the mis-designed on free5GC architecture. If an NF need to send and wait for a response, but other NF also sending request and wait for it’s response, free5GC will potentially get deadlock. We are fixing this problems and will give the refactor patch in our next release.
