I installed 9.4.3b2. I haven't seen any "too many open file  
descriptors" messages so far.

"sockstat | grep named | wc -l" shows me much less listen bind  
versions. During the whole night and at this early time in the morning  
we just have 40-150 open binds.  Maybe all our customers are enjoying  
their summer hollydays or 9.4.3b2 handels it much better.
