Dear,

We have two „run time“ alarms in DMAs which are permanent - can't find reason for it. Elements which were cause of that alarm work fine and in their logs there are no obvious reason for it.
DMA3 - Thread problem in SLProtocol.exe: [Elico ASDU/1.0.0.0] 0206_FM3_DT - ProtocolThread [+ 1 pending] )
DMA1 - Thread problem in SLProtocol.exe: [Elico SCU-06/1.0.0.1] 0366_FM_PA - ProtocolThread [+ 2 pending] )
-
We restarted DMS but after few minutes they were on again with same root times.
Those elements use serial protocol for communication and there are possibilities that time outs in connections and run time errors in QA occurs. Investigating DMA Watchdog logging those two alarms are also present. One log is below:

We noticed that in Cube view - System Center, Agents, Agent Alarms, line Show agents alarms stay DMA1 (0 errors, 1 timeout, 0 notices ), DMA3 (0 errors, 3 timeout, 0 notices ), - zero error? When click on link to table, there are earlier mentioned run time errors.
-
What is mechanism for auto clearing RTE alarms?
What can we do to remove those alarms?
How can we deeper investigate possibilities of that Alarms?
-
DMAs are 4 in cluster, 9.6.0.0-8578.

Thank you!
