One question that regularly comes up on the discussion forums is confusion around the linger keyword that occasionally shows up when doing a status enquiry using LMTOOLS or LMUTIL. Customers will run a status enquiry to find out which users have licenses in use and they want to know why some user entries include a linger value, e.g., (linger: 432000), and what that value means.
The addition of a linger keyword indicates a license that has been borrowed. The numeric value indicates the amount of time (in seconds) that the license will be in a borrowed state before it is automatically returned to the license pool.
John Smith SERVER1 SERVER1 (v2.000) (CCN12374804/27000 102), start Tue 5/25 8:46 (linger: 432000)
This linger value indicates the license was borrowed for 5 days. This is determined by dividing the linger value by 86400 (60 seconds * 60 minutes * 24 hours = 86400 seconds). This number always indicates the total borrow time for the license and not the remaining borrow time. It's good to remember that the start date and time for borrowed licenses is always reset after a server restart. For example:
John Smith SERVER1 SERVER1 (v2.000) (CCN12374804/27000 201), start Tue 5/26 9:11 (linger: 432000)
Notice that the start date and time is different – the license manager was stopped and restarted – however the linger value remains the same for that borrowed license. For this reason, you should not try and calculate the borrow period based on the start date and time in the server status. Accurate information about when a borrowed license will expire is available in the client application.
When you start an AutoCAD that is using a borrowed license you will see the following dialog:
