Open5GS Release, Revision, or Tag

Open5GS v2.7.1-23-g02d302b

Steps to reproduce

I'm not sure exactly how to reproduce it, but seems to be related to when multiple UE devices constantly attach/detach. We run some automated tests on all of the UE (20 in total) where there are numerous attach/detach happening for all of them simultaneously and this seems to be able to trigger this assert.

Thank you for the information, will test it ASAP!

Hello,

Thank you! looks like I can not reproduce this issue anymore.

@acetcom I have another question. Is there some mechanism that automatically reloads the MME Daemon?

I see that 3 nights in a row it has been reloaded right at midnight:

@emilstt

Thank you for the update! It's great to hear that the issue is no longer reproducible.

Regarding your question, Open5GS does not automatically reload the MME Daemon. It seems that your system might be sending a kill -HUP signal to the process, which triggers a reload. You may want to check your system configuration or any monitoring tools that might be sending this signal.

Let me know if you have any further questions!
