Thanks for the report.

We have seen a few of these reports on mod-pagespeed-discuss and believe it is 
related to usage of the threaded MPM, which we have not yet tested.  Our 
initial offering is tested on the pre-fork MPM.

If you would like to help adapt mod_pagespeed to the Threaded MPM we'd love to 
work with you.

I was not complete the last time: I'm using mpm-itk. It's based on the 
traditional prefork MPM: http://mpm-itk.sesse.net/

There are two unrelated issues here.

john.clegg.nz reports Poll success status 0 (111) which means "timeout 
requesting URL".  We've seen this elsewhere and need to track it down.

leonbogaert reports issues that look to me like the directories set up for 
mod_pagespeed to store cache files and other files are not writable.  Leon, can 
you investigate that?

So Leon, I think you have a setup issue.  The first error you reported was:

[Thu Nov 04 17:36:27 2010] [error] 
[1104/173627:ERROR:net/instaweb/util/google_message_handler.cc(35)] Could not

css,

Can you take a look at whether your httpd server has write access to 
/var/mod_pagespeed/cache?  If not, you can edit pagespeed.conf to point to a 
location where you do have write access. 


And both of you: please be sure you are using our latest binary distribution, 
which was released Nov 8, 2010.

Could you verify by looking at the X-Mod-Pagespeed header in Firebug from your 
HTML file?
