User reported that they are seeing multiple "InstanceNotFound", error and PRQueueException are logged in the PegaRules.log file.


Steps to Reproduce

Not Applicable

Root Cause

A defect in Pegasystems code or rules

The processing mode for few Services is set as Asynchronous, this can leave queue items with status as "Immediate".
Such queue items should be processed separately.


Perform the following local-change steps:

1. Create a custom Agent in your application ruleset, similar to “ProcessServiceQueue” in “Pega-IntSvcsruleset.
2. Use “ProcessImmediateQueueItems” Activity instead of “ProcessQueue”.
