Object reference not set to an instance of an object

Hi everyone,

 

one of our end users reports that on occasion when he kicks off a test it immediately fails and Load Generators go to 'Non-Operational' status.

 

In the PC server log file I see this error.

 

2019-12-19 04:05:30,716 [11312] [202] ERROR HP.PC.DataProcessor.DataProcessorManager - DP Task error reported: Process HP.PC.AnalysisWrapper abnormally terminated for task id: 8585 [Context: 7b5c794f-5893-4eb6-9f22-6c1566ea2b5a] [FullContext: QCServer:http://QCServer/qcbin UserName:UserName Domain:Domain1 Project:Project1QCRunId:7677 TimeslotId:26127]

System.NullReferenceException: Object reference not set to an instance of an object.

 

Then we see a series of timeout errors like this...

 

 

2019-12-19 04:10:44,744 [11312] [30] ERROR HP.PC.Host.Management.BL.Model.HostChecks.RemoteChecks.LGLightWeightConnectionCheck - Timeout connecting to LG caw0211aa014 [Context: 001b2b3d-e686-439d-9689-1e4771a3d71d] [FullContext: QCServer:http://QCServer/qcbin UserName:_pc_system_ Domain:DEFAULT Project:LAB_PROJECT]

The issue does not happen every time.
