This exception is thrown even in scenarios when list is modified outside the iterator within the same thread/user context. Check the closeinteraction activity if it trying to modify (like removing or adding an element to list) after getting the iterator but outside the iterator loop.

This seems to be a product issue as error is coming from ClipboardPageImpl class -
at java.util.HashMap$HashIterator.nextEntry(HashMap.java:922)
at java.util.HashMap$ValueIterator.next(HashMap.java:950)
at com.pega.pegarules.data.internal.clipboard.ClipboardPageImpl.clearMessages(ClipboardPageImpl.java:3869)
If someone from Pega can have a look at this class they might get an idea.
