Hi,
Error occurred during reading below line: timer t3103 0
I may be wrong, but it's probably related to recent change:
http://git.osmocom.org/openbsc/commit/?id=ab2454e776f1a4bc4977ef48ec2844600f...
In short, it doesn't make sense to set '0' value to any timer. So, updating the software, please also keep your configuration updated ;)
With best regards, Vadim Yanitskiy.
