Customer was seeing many tasks sitting in "INITIAL" state when looking at the Admin Console.
Rebooting the DispatcherClient seems to get things aligned, but the problem appears every few hours.
SolutionIn this case, the customer has many DipatcherClients (11). The cleanup values in the tc_disp\DispatcherClient\conf\Service.properties were enabled on all DispatcherClients. In doing so, each DispatcherClient was cleaning up all the time. That shouldn't happen.
My recommendation is to turn all cleanup values OFF on all but one DispatcherClient. Let only one do the clean up.
Contents of one tc_disp\DispatcherClient\conf\Service.properties (default)
Service.RequestCleanup.Successful.Interval=60
Service.RequestCleanup.Successful.Threshold=480
Service.RequestCleanup.Successful.DeleteLogs=true
Service.RequestCleanup.UnSuccessful.Interval=120
Service.RequestCleanup.UnSuccessful.Threshold=2880
Service.RequestCleanup.UnSuccessful.DeleteLogs=true
Contents of the rest of tc_disp\DispatcherClient\conf\Service.properties
Service.RequestCleanup.Successful.Interval=0
Service.RequestCleanup.Successful.Threshold=0
Service.RequestCleanup.Successful.DeleteLogs=false
Service.RequestCleanup.UnSuccessful.Interval=0
Service.RequestCleanup.UnSuccessful.Threshold=0
Service.RequestCleanup.UnSuccessful.DeleteLogs=false
After the user updated the Service.properties files, it was stable.
