   > @westonpace Have you seen this problem? (Joining with multiple threads is

   I'm not aware of any current issues like this.  That being said, the join 
code is pretty complex, so I would not be surprised if it was the culprit.  
Getting some kind of reproducer will be essential though.
   
   @stenlarsson , you mention that you have several joins.  Are they chained 
together or parallel?  For example, chained would be "join a and b and then 
join c to the result and then join d to the result" and parallel would be 
something like "join a and b and also join c and d and then join the two 
results together".
   
   Also, what kinds of joins are these?  Are they left inner joins?
