Comment (by billnbell):

Not sure why we get this on retry. We confirmed that is happens on

"x-wap-profile: "http://wap.samsungmobile.com/uaprof/SM-G870A.xml"",

Also, this looks weird:

"X-Varnish: 10944623", "X-Varnish: 10944624",

Workspace overflow.

What's in your vcl_backend_fetch{} and vcl_backend_response{} ?

Try increasing `workspace_backend`.

Comment (by billnbell):

What does s,f,r,e mean? Does it mean that I went over by 52256 bytes? It
seemed like we were only doing 5 retries. Why would it need more than the
default fix for these parameters?

Should I try both workspace_backend and workspace_client? What are the
issue with increasing this? Is 252144 a good size?

Here are the 2 functions you requested.

If I comment out the following section, the problem goes away. The max
retries is the default, so it should stop right? Or is it infinite
looping?

if ( beresp.status >= 500 && beresp.status < 600) {
return(retry);
}

Here ya go:

sub vcl_backend_fetch {
if(bereq.http.X-Backend-Type == "m") {
set bereq.backend = m.backend();
} else if(bereq.http.X-Backend-Type == "hg_tips") {
set bereq.backend = hg_tips.backend();
} else if(bereq.http.X-Backend-Type == "hg") {
set bereq.backend = hg.backend();
} else if(bereq.http.X-Backend-Type == "articles") {
set bereq.backend = articles.backend();
}


if(bereq.url ~ "(?i)^/(?!provider-search)[^/]+-directory(/[^/]+)?/?$")
{
unset bereq.http.set-cookie;
unset bereq.http.Cookie;
}
return (fetch);
}

sub vcl_backend_response {
if ( beresp.status >= 500 && beresp.status < 600) {
return(retry);
}
if ( beresp.backend.name ~ "(web|mobile|hg3)") {
if(bereq.url ~ "(?i)^/error$" && beresp.backend.name ~ "mobile" )
{
set beresp.status = 500;
}
