Thanks Radim, so the problem is that the master node is exhausting the OOB threads because they are stuck waiting for the index writes? Assuming I understood, I agree: we should do as you suggested.
Sorry for asking the obvious, but I've missed the problem description; I only heard that you've found a deadlock. Is there a JIRA related to this conversation?
