jail + zfs disque space bug ?

[nORKy]

Hi,

I have a problem with a jail that runs php-fpm and apache.
The jail is eating my disk space (38G per week).
When I stop and start the jail, the space come back.
Does someone known why ?

I don't find any bugging files( with df, du, zlist, ...).

Probably an unlinked file kept because it's still open.
