No I have not encountered OOM exception yet with current field collapse patch. How large is your configured JVM heap space (-Xmx)? Field collapsing requires more memory then regular searches so. Does Solr run out of memory during the first search(es) or does it run out of memory after a while when it performed quite a few field collapse searches?
I see that you are also using the collapse.includeCollapsedDocs.fl parameter for your search. This feature will require more memory then a normal field collapse search. I normally give the Solr instance a heap space of 1024M when having an index of a few million.
