uTorrent 3.3.1 won't quit and keeps reading pagefile

[whatUwant]

System: Windows Server 2008 R2 64bit SP1

uTorrent version: 3.3.1 30003

All files are downloaded to an SMB share.

There was no file being downloaded or written to the disk when I tried to exit uTorrent.

The interface disappeared as expected.

But the process stuck and would not quit:

It seemed to be reading pagefile:

It happened many times.

Any suggestions? Thanks.
