#1152: Varnish 503 Error
 Reporter:  ernatalo  |        Type:  defect  
   Status:  new       |    Priority:  high    
Milestone:            |   Component:  varnishd
  Version:  3.0.2     |    Severity:  critical
 Keywords:            |  

Comment(by ernatalo):

 the statistics Attached is was done this morning after the tests that I
 made ​​with Using siege.
 In this way I can reproduce what happens in reality: past 600/650 client
 connection the server stops to serve and Varnish produces 503 errors Guru
 The varnish server restart to server the client after a few secons. The
 varnishstat file attached are referd at startup of varnish service andt
 when i looked the first reported varnish error 503.
 I made some changes to the configuration file that I attached.
 I can beleave how many people declare the capacity of varnish to serve
 tens of thousands of requests per second with only 1 server Varnish.
 The data that we go and serve with varnish are mainly data exchange, many,
 but small. The larger object is One html page which is too big (a few
 hundred KB).

 The server are not even suffering memory as shown in the command free-m

                   total used free shared buffers cached
 Mem:              3953 2049 1903 0 128 1689
 -/+Buffers/cache:  230 3722
 Swap:             7624 0 7624

 I can't spend any more resources so I must make the decision to return to
 Squid that, although mono process, did not give all these problems of
 interpretation of the configuration.
 Thank you again for the help.
