    lmgrd - Maximum connections to the server has reached

    Windows server 2016 license servers.

     

    From server01 (TIMESTAMP 5/18/2026):

     3:20:07 (lmgrd) Attempting connection to primary redundant server server02

     3:20:29 (lmgrd) Disconnected from primary redundant server server02

     3:20:53 (lmgrd) Attempting connection to primary redundant server server02

     3:20:53 (lmgrd) Disconnected from primary redundant server server02

     3:21:15 (lmgrd) Attempting connection to primary redundant server server02

     3:21:19 (lmgrd) Established connection to primary redundant server server02

     3:21:19 (lmgrd) Disconnected from secondary redundant server server03

     3:21:19 (lmgrd) Redundant server quorum established. Master is server02

     3:21:19 (lmgrd) Starting vendor daemons ...

     3:21:19 (lmgrd) Starting vendor daemon at port 10306

     3:21:19 (lmgrd) Using vendor daemon port 10306 specified in license file

     3:21:19 (lmgrd) Started MLM (pid 4532)

     

    server03: (TIMESTAMP 5/18/2026)

     3:21:19 (lmgrd) Disconnected from tertiary redundant server server01

     3:21:40 (lmgrd) Attempting connection to tertiary redundant server server01

     3:21:41 (lmgrd) Established connection to tertiary redundant server server01

     

    server02: (TIMESTAMP 5/18/2026)

    3:20:08 (lmgrd) Warning: Maximum connections to the server has reached. Please disconnect some clients from the server

    ...

    3:21:11 (lmgrd) Redundant server heartbeat to server01 timed out

    3:21:11 ((lmgrd)) Loop info: MT:3 VD_HB:58 reset:3 clients:1 fd:1 main:0

    3:21:11 (lmgrd) Disconnected from tertiary redundant server server01

    3:21:19 (lmgrd) Established connection from tertiary redundant server server01

     

    There are many references to https://docs.revenera.com/fnp/2025r1/LicAdmin_Guide/Content/helplibrary/Maximum_Client_Connections_to_License_Server.htm to increase LM_SERVER_HIGHEST_FD but it does not seem relevant here clients:1 fd:1 suggests one client and 1 file descriptor? When server02 is looping there was a maximum of 300 ESTABLISHED TCP connections.

     

    What is interesting is that "Maximum connections" message appears before heartbeat and loop info message on server02? So is "Maximum connections" a catch all error? If heartbeat connection is lost to redundant license servers and a license query is received from a client server02 has to queue as it cannot process when heartbeat is lost?, so in this case could a single query cause "Maximum connections" message to be logged as lmgrd knows due to missing heartbeats its not able to process requests?

     

    Is "Maximum connections" message a catch all error? LM_SERVER_HIGHEST_FD link only seems relevant to genuinely busy license servers and doesn't seem to apply to us.

     

    Up until failure occurred the vendor daemon was running on server02 (it was the master?), we don't understand server01 logs in same second server02 is identified as master it tried to also start the vendor daemon?

    From the time the first "maximum connections" message is logged, to the "heartbeat timeout" being logged there is nominally a 60+ second time difference. So the question is setting HEARTBEAT_INTERVAL more relevant where network or server latency spikes might occur? (https://docs.revenera.com/fnp/2022r3/LicAdmin_Guide/Content/helplibrary/SERVER_Lines.htm).

     

    Anyone have any ideas please, this is a long outstanding issue for us.

     

    Best Regards - Colin

      Hi Xing,

      Let us know if you are still facing this issue, so that we could raise a support request for the license checkout issue.

      Regards,

      Sunil.

      Revenera customers who are entitled to FlexNet Publisher Licensing can download lmreporter in the Product & License Center under "FlexNet Publisher Licenses & Tools".

    We've recently signed up for Flexnet Embedded and Flexnet Publisher. I've just about figured how to place the code in our product to make use of licensing.

    But I'm completely stumped as to how to generate license keys for our product ?

      @SpaceDev​ licenses can be generated using FlexNet Operations. If you did not purchase FlexNet Operations you'll have to generate license keys manually using provided utilities. Support can provide further details through a support case if required.

       

      Thanks,

      Jim

      Hallo @mrathinam (Flexera Software)​ Thanks for the response. Unfortunately, the publisher doesn't operate any FlexLM infrastructure themselves - they only ship the license files. Security hardening of the 

      lmgrd daemon on Linux is a question about FlexNet Publisher itself, not about the publisher's product. Does Revenera have any official documentation (e.g. a security hardening guide) for running 

      lmgrd under systemd?

      Best regards Oliver.

    Unable to list features for license file 1999@flex.cd-adapco.com

    Hi Community,

    I'll say upfront that I am not a FlexNet user: I use a software by Siemens (Star-CCM+) which handles licensing through FlexNet. Siemens Support was not able to help so I am trying with this forum, apologies for my ignorance.

     

    Basically, the software cannot connect to its license server (1999@flex.cd-adapco.com) only when I use a certain ISP (TIM, I am from Italy), whereas everything works fine if I use other ones.

     

    The error is the following:

    Unable to list features for license file 1999@flex.cd-adapco.com

    Unable to check feature 'server_id', line 6852 :

    FLEXnet error: (-15,10032)

     

    Troubleshooting I already did:

    Trying DNS 8.8.8.8, trying a VPN, allowing software and ports via the antivirus and the firewall.

     

    Would you have any suggestions? Thank you!

     

    Stefano

      Hi @StefanoCampagnolo​ As per your statement, it clearly indicates that TIM’s network is blocking or interfering with the FlexNet license traffic. You will need to check whether any network rules or restrictions are configured on the TIM side. If so, please ensure that traffic to both the lmgrd and vendor daemon (VD) ports is allowed.

       

      Alternatively, you may reach out to TIM support and report this issue for further assistance. Please ask TIM to allow outbound TCP traffic to the FlexNet license server ports.

      Best Regards,

    Hi, we use FlexNet Publisher 11.19.6.1. We can create a report log but can’t read it. Is special software required, or can lmutils output a readable file? How does this differ from the debug log? We need historical concurrent usage, peaks, and trends.

      Hi @jbryant@sram.com​ ,

      You would need a special software called Flexnet Manager for Engineering applications (FNMEA) to read the report logs.

       

      You could also try enabling the extra logging by enabling the ls_enable_verbose_dlog flag in lsvendor.c and use lmreporter to analyse the report to see if this helps with your use case.
