Summary

This article explains how an extra license is checked out when a client machine reconnects to network.

Question

1. check out once license "f1" on one client machine. Confirm there is a message in debug log;
   18:07:22 (demo) OUT: "f1" user@clienthost
2. Unplug client machine's network cable and wait for several minutes.
3. Plug in client machine's network cable, then we can see one more licene is checked out on license server;
   18:08:31 (demo) OUT: "f1" user@clienthost
   In this case, client only uses one license but there are two licenses checked out.

Answer

This is expected behaviour.

On the license server side, it won't reclaim an inactive license immediately. It waits for a period which is set by TIMEOUT/TIMEOUTALL in options file. So the inactive license may stay checked out for this period of time.

On client side, when it is disconnected from server. Heartbeats will try to reconnect to license server, and once the client reconects to license server. It will check out one more license.

Since the license server will reclaim inactive licences. This shouldn't cause any decrease of license pool. As customers can adjust TIMEOUT/TIMEOUTALL to set how long server will wait before reclaiming inactive licenses.
