Root Cause
The root cause of this problem is a defect in Pegasystems’ code/rules. A diagnostic warning is output as an ERROR for large arrays.
Resolution
The explanation for this behavior is as follows: This is not an ERROR but more of a DEBUG or INFO as the declare page continues to load and writes this log entry when the list size is > 1000 to alert the requestor to check the size of the declare page if it can be reduced.
This issue is resolved through the following local change:
Update prlogging.xml to set FATAL level for com.pega.pegarules.data.internal.clipboard.PropertySet so ERROR is suppressed (this is the only log entry in the class)
Add the following in the prlogging.xml
<category name="com.pega.pegarules.data.internal.clipboard.PropertySet">
<priority value="fatal"/>
</category>
