problem with Defragcron , Tru64 4.0G & dev/null



Managers,

I seem to have a somewhat strange problem, on a DS20 running 4.0G Patchkit4,

every morning around 04:50 /dev/null was changed from a system file to a standard normal file, obviously not correct. By a process of elimination it appears that the daily defragcron job was responsible (since I commented it out in the crontab the problem has not re-occured). however we also run a defragment by directly calling defragment once a week & this seems not to cause a problem.

In the short term the problem has been resolved but I would like to re-enable the daily defrag if possible. Has anyone seen a similar problem ?
