<p class=MsoNormal><span lang=FR>Hi,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=FR><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>We’ve got a strange behavior with
varnishncsa : some requests that we can see in varnishlog are missing in the
varnishncsa logs.<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>We can clearly see that with Healthchecks
from our BIGIP (We’ve got 4x Varnish behind 2x BIGIP).<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The BIGIPs are doing 1 request every 5
seconds that we can see in varnishlog. In the varnishncsa logs, we can’t
see every healthcheck request.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Sometime, we have no log at all for 3 or 4
minutes and then the logs reappears. We’ve done tests with or withour
load, and the behavior is the same.<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>Any idea ?<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>Thanks for your help !<o:p></o:p></span></p>
