License Server keeps exiting saying hostid is invalid

[JagadeeshN]

Hi Team,

License Server keeps exiting often. like every couple of days. Eventhough the Host IDs are same on server and license file. Please look at below logs.

10:46:14 (IPASSI) Wrong hostid on SERVER line for license file:
10:46:14 (IPASSI) C:\licensing\Aveva\IPASSI\FNP1116\IPASSI.LIC
10:46:14 (IPASSI) SERVER line says VM_UUID=235D2242-2FBC-336A-17CC-8F28358D33E7, hostid is VM_UUID=235D2242-2FBC-336A-17CC-8F28358D33E7
10:46:14 (IPASSI) Invalid hostid on SERVER line

Flexlm Ver: 11.16.2

Thanks & Regards,

Hi @JagadeeshN  ,

We have got this issue reported in past ,but unfortunately  we were unable to reproduce it in house so engineering is working on a  customized kit with extra logs which can be run at your environment to understand the root cause . If you want you can raise a case with us for tracking purpose.

I tried raising issue. Was fasing some problem in raising the issue on Friday and Monday. Let me try today and raise a ticket.

Dear Team,

2 of our customers issue the same problem, using Flexnet  V11.16.2. Curiously, it happens more often during week-end so they have to restart the system every weeks. For now, the "only" solution was to use the MAC address instead of the VM_UUID. What is the solution ?

Regards,

Jean-Pierre

Hi  @jpl_3894  ,The issue is still under assessment .However I would recommend you to try the below

With static analysis it looks to the issue might not occur if VM_UUID is fetched as vendor-defined hostid. The issue only reproducing, i.e server exits with invalid hostid, when VM_UUID is fetched directly. For vendor-defined hostid functionality keep trying to fetch the valid hostids for certain iterations before exiting. 

• Can you try and check once with node locking the SERVER line with VM_UUID as vendor defined hostid I have attached the files vendor_hostid and counted.lic
   for reference. IN license file while adding the VM_UUID ignore the string VM_UUID= and just add the value.
• Please run lmcrypt on the machine where we want to run the license server to generate the valid license file.
• Share the server logs after running the Server continuously for the duration under which previously it exits with invalid hostid.
• If the workaround works then we will implement the solution accordingly.

I have the same  issue on some customers, I have try a VDH using 

lc_hostid(lm_job, VM_UUID, buf); 

And time to time (after 4/5 hours) lc_hostid return a empty buf (the next call of the function returns the right value)

and the result is SERVER line says VDH=xxx , hostid is VDH=xxx

FlexNet Licensing Service is running

@jyadav Was this issue resolved or a workaround found? Some of our customers are also facing this issue (11.18). Thanks!

@ameganat1  ,

Yes , the functionality is enhanced in 11.18.3 kit that provides the extra safeguards to fetch the VM_UUID value. Incase VM_UUID is not fetched then it will be fetched in successive attempts to fetch VM_UUID. There is high possibility that VM_UUID will be fetched in one of these attempts. The server will behave as expected without any impact. So please try in latest kits .
