Re: [SR-Users] t_relay dying ?

Many thanks for your help. I've applied the patch, recompiled and I see no difference unfortunately. The ACK is not forwarded, and execution after t_relay stops.  I've set the debug level to 4 and captured the traces - I believe the section dealing with the ACK is there:  https://pastebin.com/TG03YQWC KR J.
