#813: Varnish 503's w/ FetchError straight read_error: 11
 Reporter:  ntang     |       Owner:  martin
     Type:  defect    |      Status:  new   
 Priority:  high      |   Milestone:        
Component:  varnishd  |     Version:  2.1.2 
 Severity:  major     |    Keywords:        

Comment(by ntang):

 It shouldn't have been a timeout... here's how long it takes when I query
 Apache directly:

 [root at cc20-43 ~]# time curl --head --header "Host: [snip]"
 HTTP/1.1 200 OK

 sys     0m0.005s
 [root at cc20-43 ~]#

 As you can see, it's returning the file in around a quarter of a second.

 We are planning on upgrading to 2.1.4 to see if it fixes it, but right now
 there's no 32 bit RPM, so we need to build one ourselves and fixing the
 problem quickly was our top priority.

 (For now we're just routing requests for mp3 files straight to Apache,
 around Varnish, and that's kept things moving smoothly, as we don't get a
 huge number of requests for them and we've got the capacity there.  But
 obviously, we'd like Varnish to serve all of this content eventually.)
