I am very frequently getting the error ' Unable to select between versions' error. To resolve this issue I have to either restart the server with clear cache or remove the corresponding rule from the VT table.
Do we have any HFix or any configurations to resolve this issue?
Thanks for confirming the Pega version. As per your response, you are seeing this error only on tracer and not seeing in PegaRULES log? Ideally we must be having rule resolution related exceptions in PegaRULES log.
We want to look at the exact stack trace and error message to provide some recommendations.
