tcp_s is bad!!! Exiting - Arnold User Guide

One reason for this error is that some other process is using port 2080

In the lmgrd debug log file, you'll see this:

20:50:07 (adskflex) Server started on REMFDXQFB2 for:        
20:50:07 (adskflex) 86985ARNOL_F (consisting of:                86985ARNOL_2018_0F)

From the License Administration Guide, the -15 error:

Cannot connect to license server system.

The server (lmadmin or lmgrd) has not been started yet, or the wrong port@host or license file is

being used, or the TCP/IP port or host name in the license file has been changed.

Windows XP SP2 platforms have a limit on the number of TCP/IP connection attempts per second

that can be made, which your application may have exceeded. Refer to the manufacturer's

documentation on how to change this limit.

On Windows, you can use netstat and tasklist to find out who is using port 2080:

 C:\\Users\\blairs>netstat -ano | findstr 2080


  TCP   0.0.0.0:2080          0.0.0.0:0             LISTENING       18612
  TCP   [::]:2080              [::]:0               LISTENING       18612


C:\\Users\\blairs>tasklist  /SVC | findstr 18612

rlm.exe                      18612 RLM-SolidAngle

In the example above, you can see that the user tried to use an Autodesk license with the RLM license server.

The RLM and Autodesk (flexlm) license file formats are very similar. In particular, the Autodesk license has this VENDOR line:

 VENDOR adskflex port=2080

RLM reads that line and tries to start the adskflex ISV on port 2080. That fails, but RLM ends up listening on port 2080.
