ofer fort commented on SOLR-1990:
---------------------------------

I am not sure, still investigating.
At a specific moment i had two threads trying to delete two documents, and a
few others that were adding documents.
The ones deleting were both parking(waiting on the lock), so my big concern
is that it's actually a deadlock, but still not sure

two thread with:
