I tried everything:
service varnishlog start
- logs everything
varnishlog -D -c -m TxStatus:503 > /var/log/varnish/varnish.log
- doesn't seem to be doing anything
varnishlog -c -m TxStatus:503 > /var/log/varnish/varnish.log
- only logs until I close my SSH connection
I'm out of options, any help?
Note: varnishncsa is not an option, since it doesn't tell me which error causes the 503. I'm running Varnish 3.x (latest) and CentOS 5.8 with Apache 2 as backend.
