----------------------+-----------------------------------------------------
 When setting saintmmode in vcl_error, repeated requests (5+/s) to pages
 that return errors(500) caused varnish to go into 503 mode, backend was
 still reported as healthy, but all misses(not only to the page that failed
 with 500) are 503 and are 'connection not attempted' in varnishstat. Hits
 were still ok.

 {{{
 if (beresp.status >= 500 && beresp.status < 600) {
   set beresp.saintmode = 30m;
 }
 }}}
