<div>Hi,</div><div><br></div>Have you tried bypassing varnish by either removing it or doing a return(pipe); as the 1st instruction in your vcl_recv() and see if you still get the 302? If not, it *could* be varnish, if yes, it is your backend application that send a 302.<div>

<br><font face="sans-serif"> Been running varnish-3.0.2 revision
55e70a4 for a couple weeks using -smalloc and 6G. Got several of them and
they run fine for a couple weeks and for the 2nd time now the first cache
has stopped serving a key css file and returning a 302. I don't cache the
css and I also don't implement any 302 redirects via varnish.</font>

<br><font face="sans-serif">Any ideas why I would get a 302? I track
varnish memory using cloudwatch (in AWS) and at the time of restart it
was at 65% and had been on the decline for a couple hours from 88%. The
total Ram on the box is 7.5G so 90% is about the limit varnish will hit.
Have I not allowed enough RAM for worker threads?</font>
