Had the same issue with debian etch with default installs.

I had a look at the source code for APC and it appears TTLs in 'apc_rfc1867.c' are hardcoded to 3600 seconds.

By editing these (ugly hack ;), recompiling and putting the new apc.so in place of the old one it seems to have worked for me.

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

Latest CVS now has a apc.rfc1867_ttl INI option.  This will allow you to configure the rfc1867 TTL if your uploads are going to last longer than 3600 seconds.  Please try out latest CVS and re-open this bug if this does not fix your problem.  Thanks!

i still have these problem. When the upload files needs more then exactly one hour and zero seconds the return value of the apc_fetch is null but the upload works on.
