The license of Matlab 2019b on gpu7 has expired

[Donghan Wang]

Predrag,

Thanks for the information. I restarted the Matlab license manager on GPU7.
It works now.

The lmstart command writes to /var/tmp/lm_TMW.log. It would fail due to the
ownership issue (shown below). So it seems only the auton-local account can
restart it on computing nodes.

[dwang at gpu7 etc]$ ./lmstart
    Error: Cannot write in logfile ($LM_LOGFILE).
           LM_LOGFILE = /var/tmp/lm_TMW.log
                        -rw-rw-r--. 1 auton-local auton-local
           You are:     uid=2043(dwang) gid=2043(dwang)

Thanks,
Jarod
