sandboxd message

[Craig Treleaven]

Hi:

I re-purposed a Core2 Duo mini running 10.7.5 over the weekend.  I'm 
trying to set up Time Machine to backup the machine and it is running 
very slowly (est 20+ hours for a 56 GB backup).

It may not be related to the slow Time Machine backup, but I'm 
getting the following Console message periodically:

>14-03-17 12:49:00.695 PM sandboxd: ([1508]) mdworker(1508) deny 
>file-write-create 
>/opt/local/var/macports/home/Library/Preferences/com.apple.LaunchServices.plist.lockfile

The file
/opt/local/var/macports/home/Library/Preferences/com.apple.LaunchServices.plist.lockfile

does not exist.

Neither does
/opt/local/var/macports/home/Library/Preferences/com.apple.LaunchServices.plist

Strangely enough, I have set Spotlight to ignore everything under 
/opt, so I'm not sure why mdworker is looking in there.

I have run Disk Utility's verify disk a couple of times, no problems found.

Can anyone shed some light?
