 I raised to 10000 and still had same problems.

 I noticed problems once I started using multiple auths (I first tried 4).
 But sometimes it worked. I raised it to around 15 to get it to
 consistently fail. (Even it sometimes worked with 15 too.)

 The 50 was on a different system just to quickly verify that it worked
 elsewhere.

 I am researching to find out why a Unix socket would return "Connection
 refused". Maybe due to no longer listening? Maybe some queue is
 temporarily full?
