Hi there.

Those all seem to suggest that the wrap value is...

7,000,000 - 2,805,696
6,000,000 - 1,805,696
5,000,000 - 805,696

...in each case = 4,194,304 = 4 * 1,024 * 1,024

Memory says that blocks are normally 512 bytes, which states that it's
wrapping at a 2 Gigabyte limit. Mmmmmmm...that figure seems to ring a
bell...am I right in thinking that on 32-bit Linux systems, there's an
effective file limit of 2 Gigabytes ???

> Is it in Quota utils or in the kernel?

That I can't answer, sorry...

Best wishes from Riley.
