Connection reset – legacy filter required

very interesting indeed Franck160!

Could you guys try the apache config change as described here instead of your “quick (and dirty) patch”?

in httpd.conf:

<IfModule mpm_winnt_module>
   ThreadStackSize 8*1024*1024
</IfModule>

To Futtta and Franck160,

ThreadStackSize is definitely solving the problem!

It’s wow again ??

Now, default theme (twentyfourteen) is now working perfectly on my localhost with everything minified (including the css file) !

As Include conf/extra/httpd-mpm.conf was already uncommented in the httpd.conf file, the change as been inserted as follows in httpd-mpm.conf instead:

# WinNT MPM
# ThreadsPerChild: constant number of worker threads in the server process
# MaxConnectionsPerChild: maximum number of connections a server process serves
# Adding ThreadStackSize on 2014-01-04
<IfModule mpm_winnt_module>
    ThreadStackSize    8388608
    ThreadsPerChild        150
    MaxConnectionsPerChild   0
</IfModule>

8388608 being equivalent to 8*1024*1024… (see How do I increase the stack size for Apache running under Windows 7?).

Admittedly, the contribution of Franck160 was a nice (and a dirty) one, but changing the ThreadStackSize is more elegant.

Now going back to my ongoing project with a smile…

Thanks to both of you and have a nice day!

?? Yes! you found the correct workout ??

Note that in my case,
WP – 3.8
Autoptimize 1.8
W7
Apache 2.2.21
PHP 5.3.13
MySQL 5.5.16

ThreadStackSize 8*1024*1024 didn’t work… but ThreadStackSize 8388608 did ??

So complete solution is:
httpd.conf:

# Server-pool management (MPM specific)
Include conf/extra/httpd-mpm.conf

and into conf/extra/httpd-mpm.conf

<IfModule mpm_winnt_module>
    ThreadStackSize 8388608
</IfModule>

@zakoops houps sorry, I didn’t saw your answer;).

@futtta thanks for your interrest in our answer & support! ??

Best regards – and happy new year ??

ThreadStackSize 8*1024*1024 didn’t work… but ThreadStackSize 8388608 did ??

confirmed, same here. this is pretty low-level sssht. I’ll add an entry in the FAQ explaining how Apache on Windows might mess up!

Thanks for all the help guys, but I hope I never have to dive into such mess again really ??

I’ve been looking into this even more after experiencing a similar problem on Linux (which has a default stacksize of 8MB) when trying to optimize All-in-one-buttons’ CSS.

I’ve created a pretty detailed bug-report over at YUI-CSS-compressor-PHP-port’s Github, let’s hope the developer is smarter then I am ??

did some trial and (a lot of) error and came up with;

$css = preg_replace_callback('/(^[^\{]*)(\s(:.*\{))/', array($this, 'replace_colon'), $css);

as an alternative, much simpler regex on line 294. could you guys try this one out?

Hmm, did you mean line 291? If so, the new regex DID solve this for me!!

And while I’m here thanks to all for working on this. I started a beast apparently, but I’m glad it wasn’t just something weird on my machine.

OK, applied this fix on trunk (the upcoming 1.8), which can be downloaded here.
