 I can reproduce the following frequently on the macmini system by
 attempting to run around 15 b10-auth components:

 {{{

 }}}

 Other times I get other failures like in #1850 or like:

 {{{

 }}}

 (Also often my sockcreator is left running.)

 I used the following script to generate my configuration:

 {{{

 #!/usr/bin/awk -f

 BEGIN{

   print "{\"version\": 2,";

   print "\"Auth\": {\"datasources\": [";
   print "{\"zones\": [{\"origin\": \"example\", \"file\":
 \"tests/smallzone/master.zone.file-canonical\"}], \"type\":
 \"memory\"}],";
   print "\"listen_on\": [{\"port\": 5300, \"address\": \"127.0.0.1\"}]},";

   print "\"Boss\": {\"components\": {";

   for (i = 1; i <= ARGV[1]; i++) {

     print "\"b10-auth-" i "\": {\"kind\": \"needed\", \"special\":
 \"auth\"}";

     if (i < ARGV[1]) { print ","; }

   }

   print "}}}";

 }

 }}}

 The command line argument is the number of b10-auth components to run.

 I think this is a macmini or portability issue. I can run 50 of the
 b10-auth server components on Linux fine.
