Exit code -6 means that the program was terminated by signal 6, which is SIGABRT.

Have a read through to understand what sorts of signals are possible, and the bash section of to understand how those signals become exit codes.

In the context of ROS, this probably means that something called ROS_ABORT(), which isn't very helpful. You should probably look at the rest of the output from move_base to get a better idea of why it decided to abort.

Thanks for the input! I realised the mistake I was making.
