[Bug 392204] Re: Huge CPU usage by mount.ntfs process

[Lok]

I have another update to my post #77.

We have had the same high-cpu load problem as described above today (Monday morning).
We traced it down to a Windows7 machine doing a Sunday night backup to our server.
Windows backup created a 190,251,249Kb (181GB) single file as part of its backup set.
This file causes the ntfs-3g driver to go into a spin and use 99% cpu.
Wondering if the dev team for this driver can create a file this big and see what happens to the driver.?
This problem is re-creatable.  Copy the file back onto the ntfs-3g enabled drivers and the driver goes into 99% mode again.
