Forum: NGINX SPDY patch and mod_zip crashing workers

I'm trying to get nginx 1.3.8 to play well with the SPDY patch and
mod_zip. I don't want to move to 1.3.9+ because I rely on the upload
modules that have not yet been modified to handle the chunked uploads.

When initiating a download with mod_zip, things appear to go ok until
mod_zip starts to feed the content of the subrequest into the output
handler (spdy in this case). I get this in my debug log:

I've attached the complete debug log.

Is there more data I should provide?

Hello!

It's hardly possible to get help with this, given the fact that
you are using non-latest nginx with non-latest experimental spdy
patch and have problems with 3rd party module.

On the other hand, in any case it's good idea to provide details
as recommended on http://wiki.nginx.org/Debugging, in particular
full config to reproduce the problem, and a backtrace.
