Unresponsive while repairing

I'm not 100% of the scenario that led up to this but what i know happened was:

I shut down the server while it was repairing a file (not verifying but actually repairing)
After it started up it was semilocked up. I can't change my download speed, it refuses to add NZBs from the watch folder, it won't make any connections and it's still repairing while this is all going on.

It's almost done repairing so I'll see what happens when it's done, but it's a large file so it's been doing this for over and hour now which is a big loss in download time for me.

Also I have "Pause downloading during post processing" disabled currently.

Windows 7 64bit, latest updates.


EDIT: after it was done repairing it varified another download and then I was able to adjust the speed and connections started again. I forgot to note previously that pausing and resuming had no effect besides it just changing the status from "Downloading" to "Paused". Even though there was no connections it did not switch to "Idle".

Windows isn't very good at distributing disk access over applications.
It's perfectly feasible for a low-priority program to completely saturate the disk channel.
par2 in repair mode is perfectly capable of this.
Windows performance immediately drops dramatically, to the point of being unusable.

Windows Vista and later have some disk priority options
which we will attempt to use in a later release.
