Can't restart license server

My license server wasn't logging correctly (to /var/tmp/lm_TMW.log), so I foolishly decided to restart it. However, when I restarted it (using /usr/local/MATLAB/R2014a/etc/lmstart), it said "The license manager has not started properly". Looking in the log file, I find the following:

Obviously MLM isn't getting the right IP address. Where is it picking it up from, and how can I correct it?

Thanks
