See PR# 2325. It is an old problem and I hope that it will be
fixed somedays...

I had the problem when PC-NFS clients wrote nobody owned files
to the disk. PC-NFS uses -2 as nobody userid and this has
been the 4xxxxxxxxx (don't remeber exactly) value here.
I have a rather ugly but well functioning solution here because I
don't use UID's greater that 65535: I simply map all user id's
greater than 65535 to the nobody user, 65534. This one has 5 Meg
quota space and that's all:

As you can see in my PR, the problem is quite old...
Sorry for the late reply, but I was on holidays.
