Server 2008 DFS Staging Area Always Full

I have a 2008 Server that is a sending member to 2 other 2008 R2 servers that is replicating approximately 500 GB of data. I have a separate 100GB partition and 100GB set for the staging area, however this is frequently getting full. where the DFSR server detects the staging space is above the high watermark, and deletes the oldest staging files, affecting performance as well as DFS errors saying the service encountered errors replicating one or more file because of adequate free space not available.

Now, it appears that the deltas are never being deleted automatically after they are replicated to the other servers, and it just causes them to accumulate until these errors are generated forcing the space to clear.  Are there any patches that may resolve this issue, keep in mind the parent is a 2008 Server Standard with Service Pack 2, and the other servers are 2008 R2 Standard, with SP1.

This also appears to be causing the dfsr service to crash on the the sending server.

I need help understanding why these files are not removed after they are replicated, and how this can be fixed.

You may need to change the watermark value in the registry, I can't find proper article at the moment, but search through technet.
Basically you have to convert MB to hex numbers (if I remember correctly) and that should work.
