Hi folks,
I know that my question is not directly related to webstack and OpenSolaris,
but I thought that I'd give it a try here.
I compiled varnish (2.0.2 and 2.0.3) on Solaris 10 and I'm seeing some buggy
behavior when using it. I also tried using your varnish IPS package on a open
solaris box and I don't see the same problems there, so I wonder if you did
something incorrectly and that is causing my problems.
Here is what I did:
1) I patched varnish to compile on Solaris:
diff -ur lib/libvarnish/num.c varnish-2.0.3-patched/lib/libvarnish/num.c
--- lib/libvarnish/num.c Thu Feb 12 03:15:24 2009

2) compiled and installed varnish
export PATH=$PATH:/usr/ccs/bin
VCC_CC="gcc -fPIC -O2 -shared -o %o %s" ./configure --prefix=/usr/varnish
make
make install
3) started varnish
/usr/varnish/sbin/varnishd -a 0.0.0.0:9999 -f myapp.vcl -T 0.0.0.0:9998 -t 300
-s malloc,2G
Now when I access my app via varnish, I occasionally see 503 errors and
requests hanging or taking long to execute.
I looked at the varnish logs as well as the webserver logs from my app and it
seems that when the 503 error occurs, varnish doesn't even make a request to
the backend and somehow thinks that the backend request failed and thus it
returns 503.
As I said, I just tested webstack's varnish on a opensolaris box, with the same
backend server and it works flawlessly.
Jyri, or someone else, can you please share how you compiled varnish for your
package?
thanks,
Igor
