[Openbts-discuss] Help with openbts server

[Bharat N. <bna...@ha...>]

Hello Everyone

I have been working on OpenBTS 5.0, on Ubuntu 14.04.03 LTS- i686. The software was built on the machine. This software is working in conjunction with Ettus Research USRP N200. 

I have configured the openbts program according to the OpenBTS book found on openbts.org <http://openbts.org/>.  

The issue that I’m having is after every 10 or 20 seconds Openbts crashes and then restarts itself. I have a copy of the log file for your reference. The interesting line are

Those lines keep repeating themselves until the program crashes with the following lines
