the 'lmxendutil' reported usage doesn't match with sum of all users checkouts

Hi, I am using lmxendutil to report and log the usage of license, but I found that the sum of the each user usage is not correct.

 

Here is beginning of the report message:

 #lmxendutil -licstat -host XXXX -port 6200  LM-X End-user Utility v3.32 Copyright (C) 2002-2010 X-Formation. All rights reserved.  ++++++++++++++++++++++++++++++++++++++++ LM-X License Server on 6200@XXXX:  Server version: v4.4.9 Uptime: 5 day(s) 16 hour(s) 54 min(s) 18 sec(s) ---------------------------------------- Feature: HyperWorks Version: 13.0 Vendor: ALTAIR Start date: 2xxx-xx-xx Expire date: xxxx-xx-xx Key type: EXCLUSIVE License sharing: CUSTOM VIRTUAL  20989 of xxxxx license(s) used:   <!-- see THIS --> ---------------------------------------- 21000 license(s) used by xxxxx@BBBBB [x.x.x.x]  <!-- see THIS -->   Login time: 2016-01-04 08:01   Checkout time: 2016-01-04 08:01    Shared on custom string: xxxxx:BBBBB   21000 license(s) used by yyyyy@CCCCC [x.x.x.x]  <!-- see THIS -->   Login time: 2016-01-04 08:21   Checkout time: 2016-01-04 08:21    Shared on custom string: yyyyy:CCCCC 

My point is the number in '20989 of xxxxx license(s) used'  is not equal to the each user sum up 21000+21000 = 42000.

It looks the reported total usage is about half of the each user usage. 

 

3 features have this problem but others are correct, the 3 features are:

• GlobalZoneAP
• HWHyperMesh
• HyperWorks
   

I want to know what the relationship of the reported usage and the each user usage.

Thanks.
