<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I’ve managed to get to the bottom of this. This issue is caused by the RFC1867 upload timeout in APC which is set to 3600s by default (I used apc.php to check this).
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The fix is to add the following to your apc.ini (/etc/php5/apache2/conf.d/apc.ini on Ubuntu):<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:36.0pt"><span style="color:#1F497D">apc.rfc1867_ttl = 7200 (or whatever the longest upload time you expect is)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">To further complicate matters, it seems there was a bug in APC which meant this variable was hardcoded to 3600 prior to 3.1.4 (https://bugs.php.net/bug.php?id=58738).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">With an up-to-date version of APC and after an apache restart the progress bar works perfectly

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Now all I have to do is migrate all our existing drop-offs to my new server.<o:p></o:p></span></p>
