    Description

      I start multiple clients so that they perform about 2000 queries per second.

      Eventually I receive lots of errors:

      [09/Aug/2013 02:18:20] WARNING - <RC=0x18[Connection failure], There was a problem scheduling your request, or determining the appropriate server or vBucket for the key(s) requested. This may also be a bug in the SDK if there are no network issues., C Source=(src/http.c,317)>

      Apparently I see many connections in TIME_WAIT state (60000-80000 connections):
