Database preparations used to be done in PyHSS by all services if they noticed that this was needed. The time between checking and creating the tables caused a race condition where two services attempting to create tables at the same time will result at one of them failing, we have seen this in our ttcn3-hlr-test-pyhss jobs sometimes:
I have fixed this upstream by letting only the main service (pyhss_hss) prepare the database: https://github.com/nickvsnetworking/pyhss/commit/8b8a2202c345fbb7262c9d07d03003cd2fdb819f
This means that we now need to run the pyhss_hss service in the HLR tests, so pyhss_gsup doesn't fail with:
[Database] [INFO] Waiting for the main service to prepare the database ERROR: 127.0.0.1:4222 did not become available within 5s! [testenv][pyhss] pyhss_gsup: setup script failed
