Troubleshooting: Setting up varnish 2.1.2 on OpenSolaris

Wed Jul 7 22:47:21 CEST 2010

So the fpic solved my problem with getting the -1 warning.  However, I'm
getting nothing but 503 responses from varnish.

I've updated to using this for configure:
VCC_CC="cc -fpic -shared -G -m64 -o %o %s" \
CC=/usr/bin/gcc \
CFLAGS="-O3 -pthreads -m64 -fomit-frame-pointer"\
LDFLAGS="-lumem -pthreads" \
./configure --prefix=/opt/extra

The updated VCC_CC line means I don't have to pass it every time I start
varnish.

The simplest run:
/opt/extra/sbin/varnishd -F -a:80 -b 87.238.47.204:80

I always get 503s.  When I check the vmlog, I see backend server not
available.  To further test, I upped the timeout values in a basic vcl just
in case that was the problem.  No change.

My question is, how can I figure out why I'm getting backend server not
available?  If I add a probe, I still see no outbound requests and backends
start at healthy and then become sick shortly after (where they stay).

Running tcpdump, I see no communication with the backend server during any
of this.

Where is my error?

Thanks,
Jacques
