It happened again.  The filesystem is read-only.  The logwatch log 
doesn't report anything unusual.  The Cron weekly log shows:

/etc/cron.weekly/quotacheck.cron:
quotacheck: Cannot remount filesystem /home read-write. cannot write new 
quota files.
quotaon: using /home/aquota.user on /dev/hda3 [/home]: Read-only file system


The output from mount for /home shows:
/dev/hda3 on /home type ext3 (rw,usrquota)
