So apparently the license manager for idl on canopus loses connection to the server from time to time and Bruce found out that the best way to deal with it was just to power cycle it. Yuping encountered the problem again today and tried the following and it worked.
sudo su – (puts one into root and bash shell – must have sudo privileges)
$ cd /usr/local/exelis/idl83
This is where the IDL installation is
$./bin/lmutil lmdown
This will kill all of the license managers.
$ps aux|grep lm
Make sure that all lm’s are killed
$ ./bin/lmgrd > lmgrd-201Y-MM-DD.log
imgrd starts the license managers.
This appears to fix the problem.

On 2016-05-26, joel found that the above did not quitre work without some help. I had to first create the log file with a sudo touch filename command, and then CONCAT to the log file in the above sh command by adding a second > to the first one.
