Duplicate Zlib compression kills XenForo

[Shamil]

For some reason, enabling Zlib compression, via php.ini on IIS7.5, with latest PHP, 5.3.3, seems to kills XenForo.
PHP Error:
[09-Oct-2010 15:39:51] PHP Notice: ob_end_clean(): failed to delete buffer zlib output compression. in C:\inetpub\site\library\XenForo\Application.php on line 139
It's inflated by log size by 298 times :/
Doesn't XenForo turn zlib off anyway?

NO
Use IIS dynamic compression instead.

Actually XenForo DOES break if you have any form of compression handlers enabled in php.ini. Regardless of whether it is windows or Linux or BSD...

Mike posted a fixed somewhere but I cannot find it now...

Edit: found it

Try this fix... http://xenforo.com/community/threads/fixed-browser-timeout-issue.5099/#post-81880

That could stop the zblib errors... I also had them whilst zlib output handlers were present in php.ini, the moment I disabled them it worked.

There's only one other person who's seen the error, and no fix was posted for it. Dynamic compression has been disabled.

Hmm, ok, didn't find that thread in my search. This seems to sort the issue. However, this also works:

if (ob_get_length() > 0) {
      ob_end_clean();
}

I think this is better than Mike's suppression of the output.

It does break, I have not posted it as I saw that the fix that Mike posted fixes the issue.

I prefer the method I've chosen, because it checks to see if the buffers exist.

Your fix isn't sufficient for all cases.

Your fix isn't sufficient for all cases.

My exam would throw a fit if I wanted to use @ suppression parameters lol.
Ok, you know best
