srsRAN 5g gNB running in ZMQ mode is not sending samples

[rajesh-for-work]

I brought up the ZeroMQ-based Setup of srsRAN 5G gNB (latest branch), srsRAN 5G Prototype UE and open5GS in a Ubuntu 24 OS VM configured with 4 core CPU and 8 GB RAM following the srsRAN tutorials. I used the gNB and UE config files given in the tutorial.

I am running the gNB with the below cmd
sudo ./gnb -c ../../../configs/gnb_zmq_with_open5gs_corenw_20mhz.yml

And I am getting the following output
--== srsRAN gNB (commit d2f4b70) ==--
Lower PHY in executor sequential baseband mode.
Available radio types: zmq.
Cell pci=1, bw=20 MHz, 1T1R, dl_arfcn=368500 (n3), dl_freq=1842.5 MHz, dl_ssb_arfcn=368410, ul_freq=1747.5 MHz
N2: Connection to AMF on 127.0.0.5:38412 completed

I observed that I am not getting the printing of the below 2 lines at the end of gNB execution and also in the gnb.log i dont see any RF and PHY related prints even after enabling the "all_level", "radio_level" and "phy_level" to debug in the gnb yaml file. I am suspecting that gNB is not sending any samples through ZMQ

When i am running the srsRAN ue, i see from the ue.log that ue is not getting any samples from gNB. To check the srsRAN 5G prototype ue functionality, i brought up srsRAN 5G prototype gNB (from 4g codebase) and 5g prototype gNB is able to send the samples through ZMQ and UE attach is also happening.

Rechecked srsRAN gNB configuration and also "ru_sdr" section in the gNB config which is inline to the ZMQ config given in the srsRAN config files, but still gNB is not able to send samples though ZMQ and i dont see any RF and PHY related prints in the gnb.log

I am totally blocked at this point and it would of great help if anyone from SRSRAN community can give any info/suggestions for this issue.
