Thanks so much for looking into this. I spent yesterday attempting to
get some useful debug information out of dtrace with little success -
I either ended up with megabytes of debug dumps or empty files
depending on my D script. Not exactly successful.
I've compiled with the additional -mt flag, here's my current
compilation process:
make clean
./autogen.sh
CFLAGS="-m64 -mt" CC=/opt/SunStudioExpress/bin/cc ./configure --prefix=/opt
make
make install
And I'm starting up with:
newtask -p highfile /opt/sbin/varnishd -f /opt/etc/varnish/firebox.vcl -F \
-p cc_command='/opt/SunStudioExpress/bin/cc -Kpic -G -m64 -o %o %s' \
-T 127.0.0.1:9001 \
-s malloc,1G \
-p sess_timeout=5s \
-p max_restarts=12 \
-p waiter=poll \
-p connect_timeout=0s \
-p sess_workspace=65536
Varnish seems to be a *lot* happier and panics less regularly. Panics
now all seem to suggest the error is "Connection reset by peer"
instead of EBADF

And I'm also seeing the same error occur in http_copyheader() - could
this be due to the Range: aspect of the client request?
