Spool goes crazy sometimes?

Hello,

i'm using a libz spool to save harddisc memory. Sometimes a whole
group goes crazy, the expire script with

su news -c "/usr/local/sbin/snexpire * >/dev/null"

goes crazy. It outputs thousands of lines "cannot unlink 4238423".
This effect cannot be repaired with harolds maint script. The group
must be deleted and recreated. This happens since 0.3.4a to the
running testversion. The output from snexpire blast up the cronmail,
had filled up 6Gig of harddisc space and cause a hanging system. I
found cronmails with 2 Gig.

Who got the same effect? What did the unlink mean and can this output
be reduced to one info "555000 articles not unlinked" instead of so
many lines?

Bye
