Hello,
I've been experiencing this bug ever since I started experimenting with
OpenBSC.
At first I thought it as a problem with unstable connection, but it
continued to happen even after I connected to the nanoBTS directly
through a switch.
I used Wireshark to track down the cause and discovered that OpenBSC was
responding too late to PING message from the nanoBTS. I am attaching the
pcap file of the moment.
This happens as soon as 1 hour from the first connection, sometimes it
runs okay for 18 hours but I've never seen my nanoBTS running straight
for more than 24hrs
Please take a look into the log. Any help will be greatly appreciated.
Tell me in case if you need more information
Regards,
Pierre
