OAI UE with S1 support is terminated due to System Call
OAI UE with S1 support has encountered the following error: LLLLLLLLLLLLsigwait: Interrupted system call
This is basically due to system call to execute a shell command to setup the oip0 interface with IP address allocated by EPC.
Disable this (/openair-cn/NAS/UE/ESM/esm_ebr_context.c) seem to allow the OAI UE with S1 to proceed and able to do PING. But would like to seek for a better approach.
