Spirent TestCenter: GUI loses connection to chassis after some time.
Below is some information from the logs.
When the issue occurs we have all sorts of connection issues. Here is just an example:
17/11/07 12:11:02.522 INFO 112 - fmwk.bll.base.cmd - Command.16836(LostConnectionHandler) state: Started in background
17/11/07 12:11:02.522 INFO 5112 - fmwk.bll.base.cmd - Command.16836(LostConnectionHandler) state: Running

The TestCenter then looks at the Windows PC event logs.
17/11/07 12:11:02.538 INFO 2452 - fmwk.bll.core.utils - Displaying contents of windows Application event log...
17/11/07 12:11:02.757 ERROR 2452 - fmwk.bll.core.utils - System Event: level = WARN, source = e1dexpress, date = Tue Nov 07 12:10:52 2017 message = Intel(R) Ethernet Connection I217-LM
Network link is disconnected.
We can see in the windows PC event logs that there was some ethernet connection issue and network link disconnected.
It was found that the PC had a sleep time and if no activity the network link is dropped.
It doesn’t say the PC went to sleep but if the network link goes down then the TestCenter GUI will lose connection and the GUI will give a message and close down.
After disabling sleep on the PC, the connection became stable.
Additional comments: If issue different from above but similar GUI loses connection or freezes.
Always check the logs.
Test with another PC.
Test with PC that is NOT a Virtual Machine.
Disable Windows Update.
Using a Lab Server may help.
