Dear Pablo, Daniel was adding keepalive support to the socket used to talk to the bts. This was done in commit 8c2591d95e17eb6fa868e4d886a63ac62f3ca8af of OpenBSC and somehow needs to find its way to master of OpenBSC or libosmo-abis. I think it belongs into libosmo-abis but I am not sure where exactly. Is the keepalive setting something that belongs into the e1inp_line and configuration? Do you have an idea where I should add it? thanks holger
