[srsran-users] srsgnb gets "Killed" when srsue is run.

[Joel Renjith]

*Issue Description*

*System details*

   - Ubuntu 20.04 LTS
   - GCP Virtual Machine

*Setup Details*

   - I am trying to do the srsue zermq setup given in this link : srsRAN
   gNB with srsUE
   <https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html>
   - srsRAN_4G [Version 23.04] installation done according to srsran4g
   Installation Guide
   <https://docs.srsran.com/projects/4g/en/latest/general/source/1_installation.html>
   - srsRAN_Project [Version 24.04] installation done according to srsProject
   Installation Guide
   <https://docs.srsran.com/projects/project/en/latest/user_manuals/source/installation.html>
    using *Clone and Build*.
   - ZeroMQ setup using srsRAN 4G with ZMQ Virtual Radios
   <https://docs.srsran.com/projects/4g/en/next/app_notes/source/zeromq/source/index.html>
    and Build srsRAN_Project 5G RAN with ZeroMQ
   <https://github.com/s5uishida/build_srsran_5g_zmq>

*Expected Behavior*

   - I have a setup that connects a UE to a RAN and the RAN to the Core
   using zeromq as shown in this link: ZeroMQ-based Setup
   <https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html#zeromq-based-setup>
   - When I first compose up the Open5gc container and run the gnb script
   in srsRAN_Project/build/apps/gnb/ with the config file given in the zeromq
   setup, the gnb successfully connects to amf.

   - Then when I run the srsue script, it should connect to the gnb and
   from there get connected to the core.

*Actual Behaviour*

   - When I run srsue script present in srsRAN_4G/build/srsue/src, the gnb
   process gets "Killed" and the srsue process is just stuck at "Attaching
   UE". The Open5gs container logs show that gnb connection is refused and the
   number of gnb connected is 0.
   - srsue:

    - gnb "Killed":
         [image: image.png]

   - Open5gs connection refusal:

*Steps to reproduce the problem*

   - Follow the steps mentioned in zeromq setup of ZeroMQ-based Setup
   <https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html#zeromq-based-setup>
   - I ran make  command again for srsran_4g and srsran_project to include
   zeromq

*Additional Information*

   - I tried fixing the issue by changing the gnb config file to the custom
   config file given in the srsue zeromq setup.

Any help that's provided would be greatly appreciated. Thanks in advance
