eNB failed to bind to socket

Hi Experts,

I tried to run eNB on ubuntu 16.04. USRP B210 is connected and is detected. I am using the below command to run. root@USRPB2101604LTS:/opt/openairinterface5g/openairinterface5g/cmake_targets/lte_build_oai/build# ./lte-softmodem -O /opt/openairinterface5g/openairinterface5g/targets/PROJECTS/GENERIC-LTE-EPC/CONF/enb.band7.tm1.25PRB.usrpb210.replay.conf -d

(I've used this build command: ./build_oai -w USRP --eNB) eNB failed to bind to socket. UDP: Failed to bind socket: (Address already in use:98) address 192.168.1.28 port 2152 As per my observation netstat -na | grep 2152 has an entry after loading the FPGA image.

Much appreciated quick help here.

Thanks, Sangram.
