How do I read a Maple Network Server Log File

  • Updated

The log file for a Maple Network server will tell you if there are any errors in the server. It is the most reliable way to diagnose a server and is the tool we recommend using.

When setting up a license server you'll create a text file that will work as the log file. If you're following the steps in this FAQ, then the file will be named log.txt and be located in:

Windows:

C:\Program Files\Maple Network Tools\FLEXlm\11.13.1.2\windows\log.txt

Linux:

$HOME/MapleNetworkTools/FLEXlm/11.13.1.2/log.txt

though the location may change based on where it is created and saved.

Maple Network Server Log files contain many lines that indicated various errors or statuses of your server. Below you will find examples of a healthy and unhealthy log file. As well as the causes of the errors seen in the unhealthy log file.

If your log file contains all the components of a healthy log file and none of the components of an unhealthy log file but clients still are unable to access the server please ensure that the correct ports are open on the server, the network, and the client. For more information see license server setup tips here.

 

Healthy Log File:

Start Time of Server:

03:14:15 (lmgrd) Server's System Date and Time: Sat Jun 01 2021 03:14:15 Eastern Daylight Time

FLEXlm Version and Server Name:

03:14:15 (lmgrd) FlexNet Licensing (v11.13.1.2 build 173302 x64_n6) started on mapleserver (IBM PC) (7/1/2021)
...
03:14:15 (maplelmg) (@maplelmg-SLOG@) Host used in license file: mapleserver

lmgrd Version:

03:14:15 (lmgrd) (@lmgrd-SLOG@) LMGRD Version: v11.13.1.2 build 173302 x64_n6 ( build 173302 (ipv6))

maplelmg Version:

03:14:15 (maplelmg) (@maplelmg-SLOG@) VD Version: v11.13.1.2 build 173302 x64_n6 ( build 173302 (ipv6))

License File:

03:14:15 (lmgrd) License file(s): C:\Program Files\Maple Network Tools\activate\Maple2021.lic

lmgrd Port:

03:14:15 (lmgrd) lmgrd tcp-port 27000
...
03:14:15 (lmgrd) (@lmgrd-SLOG@) Listening port: 27000

maplelmg Port:

03:14:15 (lmgrd) Starting vendor daemon at port 28010
03:14:15 (lmgrd) Using vendor daemon port 28010 specified in license file
...
03:14:15 (lmgrd) maplelmg using TCP-port 28010
...
03:14:15 (maplelmg) (@maplelmg-SLOG@) Listening port: 28010

Maple Versions Available:

03:14:15 (maplelmg) Maple (consisting of: Maple2021 Maple2020 Maple2019)

License Checkout:

03:14:15 (maplelmg) OUT: "Maple" bsmith@mapleclient
03:14:15 (maplelmg) OUT: "Maple2021" bsmith@mapleclient

 

Unhealthy Log File:

Invalid Server Name:

03:14:15 (lmgrd) "mapleserver": Not a valid server hostname, exiting.
03:14:15 (lmgrd) Valid license server system hosts are: "<server>"

If your log file contains these lines you'll need to rename your server to be the same as the name of the computer or the ip address. 

 

Same Port For lmgrd and maplelmg:

03:14:15 (maplelmg) tcp_s is bad!!! Exiting
03:14:15 (maplelmg) EXITING DUE TO SIGNAL 28 Exit reason 5
03:14:15 (lmgrd) maplelmg exited with status 28 (Communications error)
03:14:15 (lmgrd) Please correct problem and restart daemons

The lmgrd port and maplelmg port need to be different ports. You can see more information on how to declare these here.

 

lmgrd Port is Unavailable:

03:14:15 (lmgrd) Failed to open the TCP port number in the license

This could occur if something else is using the lmgrd port you declared in the license file or if the port isn't open on the server (or on the network). More information on on ports is available here. If there is another server running on the same computer using the same port number you may also get this error. We recommend that Maple Network Tools be the only FlexLM service on a given machine but if this isn't possible there are instructions on how to set this up here.

 

maplelmg Port is Unavailable:

  • Present:

    03:14:15 (lmgrd) maplelmg using TCP-port 28010

  • Absent:

    03:14:15 (maplelmg) (@maplelmg-SLOG@) Listening port: 28010

You can find information on how to declare the maplelmg port here.

 

Invalid or Missing License File Errors:

  • Invalid license key:

    03:14:15 (maplelmg) Invalid license key (inconsistent authentication code)

  • Invalid hostid:

    03:14:15 (maplelmg) Wrong hostid on SERVER line for license file: C:\Program Files\Maple Network Tools\activate\Maple2021.lic
03:14:15 (maplelmg) SERVER line says DISK_SERIAL_NUM=aa11bb22, hostid is DISK_SERIAL_NUM=cc33dd44
03:14:15 (maplelmg) Invalid hostid on SERVER line

These may occur if the host id used to activate the server isn't the correct one. If you're migrating a server to a new machine please see this FAQ.

 

Invalid maplelmg.opt file:

  • 03:14:15 (maplelmg) USER_BASED license error for Maple (INCLUDE missing)
03:14:15 (maplelmg) Please ensure that no more than 10 users for Maple are in an INCLUDE list in the daemon options file.
  • 03:14:15 (maplelmg) HOST_BASED license error for Maple (INCLUDE missing)
03:14:15 (maplelmg) Please ensure that no more than 10 hosts for Maple are in an INCLUDE list in the daemon options file.

If you have a non-floating license then the maplelmg.opt file will need to be configured. Instructions on configuring this file are available here.

 

Too few licenses for hosts/users in maplelmg.opt:

  • 03:14:15 (maplelmg) HOST_BASED license error for Maple2021 – Number of INCLUDE names (2) exceeds limit of 1
  • 03:14:15 (maplelmg) USER_BASED license error for Maple2021 – Number of INCLUDE names (2) exceeds limit of 1

If you receive this error you've designated more users or computers in your options file than you have licenses available. If you'd like more licenses, please contact your account manager at Maplesoft.

 

Incompatible maplelmg:

  • CreateProcess error code: 0xc1 File= maplelmg.exe

There was likely an error when installing Maple Network Tools please re-install Maple Network Tools to correct this.

 

lmgrd is newer than maplelmg:

  • 03:14:15 (maplelmg) Request denied: Client (11.14) newer than Vendor Daemon (11.13). (Version of vendor daemon is too old. (-83,21049))

This may occur is our vendor daemon is used with another software's version of FlexLM. Please contact Maplesoft Support with the log file and description of how Maple Network Tools is setup and we will try to assist. 

 

lmgrd is being blocked (either by another license service or Windows DEP):

  • 03:14:15 (lmgrd) maplelmg exited with status 58 ()
03:14:15 (lmgrd) Since this is an unknown status, license server 
03:14:15 (lmgrd) manager (lmgrd) will attempt to re-start the vendor daemon.
03:14:15 (lmgrd) EXITING DUE TO SIGNAL 1

This could occur if something else is using the lmgrd port you declared in the license file or if the port isn't open on the server (or on the network). More information on on ports is available here. If there is another server running on the same computer using the same port number you may also get this error. We recommend that Maple Network Tools be the only FlexLM service on a given machine but if this isn't possible there are instructions on how to set this up here.
