<p class=MsoNormal><span lang=EN-US>i am having a strange issue regarding the „director“
with 2 backend hosts.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’ve two webservers running lighty
and one frontend (running the 2.1 varnishd).<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The webs are put together as a redirector
backend in varnishd as web01 and web02.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>When web02 fails, web01 takes over the work
and everything works fine.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>When I do it the other way (web01 fails and
web02 is healthy) I got 503 (guru meditation).<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The varnishlog reports web01 correctly as
sick – but it seems to me that it is used anyway !<o:p></o:p></span></p>
