	Hello,

	Another one, but without any 'rm'. This morning, I have received a mail 
from Charlie root :

daily insecurity output for Tue Jul  5 03:15:01 CEST 2016
Checking setuid files and devices:
Setuid/device find errors:
find: fts_read: No such file or directory

	I wonder if this issue could be related to disk internal cache 
strategy. Now, both disks return :
legendre# legendre# dkctl /dev/wd1 getcache
/dev/wd1d: read cache enabled
/dev/wd1d: write-back cache enabled
/dev/wd1d: read cache enable is not changeable
/dev/wd1d: write cache enable is changeable
/dev/wd1d: cache parameters are not savable
legendre# dkctl /dev/wd0 getcache
/dev/wd0d: read cache enabled
/dev/wd0d: write-back cache enabled
/dev/wd0d: read cache enable is not changeable
/dev/wd0d: write cache enable is changeable
/dev/wd0d: cache parameters are not savable
legendre#

	Is there a hope to fix this particularly bad issue ?

	Best regards,

	JKB
