I have 3 GB ram here.
Thanks for looking into this issue. I've shared the folder with Beatslaughter too.
With default settings i was able to replicate the running out of memory issue and adding that memory size line to the PHP script didn't help either. I have found a solution it seems by making the PHP executable large address aware. Normally this is a compiler setting, but with this small tool you can patch the file yourself.
1. Download the small tool from the first post here: http://www.techpower...ad.php?t=112556
2. Pick the php.exe file in the php subfolder of xrns-sf as target.
3. Tick the checkbox which enables the flag and then press the save button.
4. Try the merge again and it should work.
If you're too lazy for all that, grab the appended php.exe and change the file with the one included.
