2023-05-29 11:12:51,345 ERROR [Thread-123 ProcessMessages] wt.wvs.workeragent.ProcessMessages - Don't know how to process exit

I am seeing this repeated message in my BGMS. Over holiday, it was written every 20-30 mins. We also had an issue with the BGMS where it was locking up, no queue jobs were processing and restart was done. I am wondering if this is related.  When I checked Server Status Max and Avg concurrency was red for the BGMS.

We used tcpdump to trace traffic back to a watchtower monitoring service. We believe it was the cause since in checking for the open port as proof WVS Services are functioning properly, it cause the agent to process garbage. Still confirming but I will close this thread if that is the case.

No clue.. but what comes to mind is antivirus software. Check to see if it might be possibly locking files?

It seems to be part of a normal CAD Agent exception messages. This is something similar:

What's strange is that is runs like a polling process every 20 seconds or so.

Hi @avillanueva 

Do you know what queue case the error? wvs, wokrflow, or some other queues?

What else the error shows? Other rows with at and so on.  Where the error is thrown can be the key.
