Hi,

I hope this is the place to ask this, if not I will delete this post. I am trying to run my own 2G network for researching purposes. I am running the following elements: - osmo-bts-trx (connecting to osmo-trx-uhd driving a USRP B205mini-i) - osmo-bsc - osmo-msc - osmo-hlr - osmo-mgw

I built all the programs from source on Ubuntu 22.04. Everything is running locally on one machine.

Everything seems to be running OK. I was able to register two different subscribers by IMSI (without providing K and OPc) and assign MSISDN tothem. They can use the default USSD codes for seeing their IMSI and their MSISDN and I can make voice calls between both subscribers. I am mostly using the default config files provided with the installation, the only changes I made to them was to point IPs to 127.0.0.1 to run everything on the same machine.

But when starting osmo-bsc and osmo-msc I get the same error on both:

Is it something I should worry about?
