 From what I recall when I was first putting my build system together, 
which I will admit was on Solr 1.4.0, I couldn't do updates/deletes 
while optimizing was underway.  I don't think 3.x was a whole lot 
different in this respect.  From the little I understand about the 
significant changes in 4.0, it is probably now possible to do everything 
at the same time with no worry.

Because they are using 3.3, I don't think they have access to this 
ability.  Given the limited amount of information available, it seemed 
the most likely explanation.  I could be wrong, and if I am, they will 
have to keep looking for an explanation.

I'm definitely no expert, and I have not tried optimizing and updating 
at the same time since upgrading to 3.x.  My indexing system 
deliberately avoids doing the two at the same time because it caused 
problems on 1.4.x.

I would certainly love to know for sure whether it's possible on 4.0, 
because I am in the process of updating my entire test environment in 
preparation for a production rollout.  If I can do updates/commits at 
the same time as optimizing, my code will get smaller and a lot simpler.
