The warning tells you that the line has been truncated because is exceeded 80 characters. The log for each bias point goes to a separate file (unless you disabled this), and it appears that the log file names are quite long. You should be able to see those log files i your project folder. Nothing will be printed in the main log until the first bias point calculation is finished, but you should be able to follow the progress in the individual bias logs. If the calculation seems to hang, you should use MPI parallelization to speed it up. You currently use 1 process only, so each bias point calculation is done in serial, one after the other.
