HTTP 400 returned for a HTTP request over 28 headers?

Tue Aug 31 15:52:05 CEST 2010

Thanks Per!   Looking at
http://varnish-cache.org/docs/trunk/reference/varnishd.html; it seems I just
need to add this in /etc/sysconfig/varnish:

DAEMON_OPTS="-a :7081 \
             -T localhost:7082 \
             -f /etc/varnish/default.vcl \
             -p http_headers=128 \                 ### NOT WORK?
             -p cli_buffer=8192 \                  ### WORKS OK
             -u varnish -g varnish \
             -s file,/var/lib/varnish/varnish_storage.bin,1G"

However, when I try to restart:

root at machine>/etc/init.d/varnish restart
Stopping varnish HTTP accelerator:                         [  OK  ]
Starting varnish HTTP accelerator:                         [FAILED]

I see nothing in /var/log/messages nor in varnishlog.

root at machine>varnishd -V
varnishd (varnish-2.0.6)

Am I using an older version?  Just did the varnish install via yum-EPEL.

Thanks
Anderson
