  That's also documented IIRC.  If you have more threads than SQL
sockets, then some threads can fail to get an SQL socket.  This is
because all of the thrreads run in parallel.

  And yes, the overwhelming majority of the time the issue is that the
DB is slow.  People configure the server to have 1000 threads and 1000
SQL sockets... and still run into the error.  The only solution there is
to fix the DB.
