Description
If I start osmo-stp, osmo-msc, osmo-bsc, and then osmo-sgsn everything works fine. However, if I start osmo-sgsn before starting osmo-bsc, the later is having problems:

Interestingly enough, the routing context is 0 in the logging messages, while I have it set to 2 in the config file.
Below is the configuration snippets for osmo-stp, osmo-msc, osmo-bsc and osmo-sgsn:

| osmo-bsc | 0.23.3 | 2 0.23.3 |
| osmo-sgsn | 0.23.4 | 0 0.23.4 |
