Hi all,
we are currently experiencing some issues with OpenBSC paired with a
sysmobts-2050. SDCCH channels are getting stick into BROKEN/UNUSABLE
state, and they don't get released. This accumulates over time and
reaches a point where we have to manually restart osmo-nitb because
there are no channels availables and the whole network breaks down.
Is it a know issue or only us? :)
This is the "show lchan" output:
