Open5gs v2.7.0
SMF crashes when multiple UE attachment attempts fail due to possible memory leak.
Please set up the environment following the instructions at https://github.com/s5uishida/open5gs_5gc_ueransim_sample_config, we use just one UE and one UPF.
#!/bin/bash
./open5gs/install/bin/open5gs-amfd &
ssh [email protected] /UERANSIM/build/runGnb.sh &
ssh [email protected] /UERANSIM/build/runUE.sh &
sleep 1.5
pkill open5gs-amfd
