UE disconnects after some uncertain interval of time

[Alan1321]

I have a working srsRAN setup, but the UE disconnects from the network from time to time. I am using

1. B210
2. PC with i7 processor and 32 gigs of RAM 512 ssd, running both epc and enb inside of a docker container
3. Motorola one 5G ace as the UE

Below are the logs from epc/enb:

I have tried changing the n_prb, tm, rrc_inactivity_timer, max_parch_offset_us, different frequencies etc. None of it helped.

Anyone faced something like this before or has idea of what the issue might be or any suggestions on what I could test/try? Thanks.
