MATLAB: Does the Network License Manager fail to start with the errno: 24 in the logfile

Question

The network license manager doesn't start. When I look at the logfile it says:

00:00:00 (lmgrd) Can't open /usr/tmp/.flexlm/lmgrdl.xxx, errno: 24

Answer 1

This can be caused by a limit on the file descriptors on your system. You can change this limit using the ulimit command in Terminal.

Before starting the license manager for MATLAB, try increasing the maximum number of open file descriptors. You can do this using the following commands:

ulimit -n 2048
ulimit -H -n 2048
