I did not spend too much looking at it, but I have noticed the following which is really strange:
You have an agent at 20224 trying to enter Ready state:
@17:34:13.6281 [0] Received from 82 (c4ab ): message RequestAgentReady
AttributeThisQueue '25061'
AttributeThisDN '20224'
AttributeAgentWorkMode 0
AttributeReferenceID 74
Then you are issuing the same requestagentready message again 10ms later from the same client (client 82)
@17:34:13.6292 [0] Received from 82 (c4ab ): message RequestAgentReady
AttributeThisQueue '25061'
AttributeThisDN '20224'
AttributeAgentWorkMode 0
AttributeReferenceID 75
TESTLV2: request queued
Here is what my first guess would be:
you had a network congestion which lasted for less than 3 seconds and caused your first Ready request from your softphone to take for example 3 seconds to reach TServer. Your agent not gettng the expected response right away, pressed the ready button again and probably it was queued at the router to. So, they arrived at Donald TServer at the same time, causing this error.
If not then check your softphone to see that you are not issuing double requestagentready! I know it sounds bizzare because probably you are using the same softphone with the rest of the agents, but this is the only thing I can think off other than that
Anything in release notes? What TServer version do you have?
