I have found the real cause of most of the problems: it's ccache configuration. I used the same cache of 15 Gb for the host (amd64) and for all jails (both amd64 and i386): the i386 jails disliked it very much. Creating a new cache only for the i386 jails fixed the problems. Maybe I will have to make the cache smaller to avoid problems in future, but for now it is almost empty and everything is fine. Thanks everybody for your help.
