/System/Library/Frameworks/SyncServices.framework/Versions/Current/Resources/SyncServer.app/Contents/Resources/upgradedb is where it's calling it from.. so SyncServer.app. Core services in the Mac.
Would you have Missinc Sync app installed?
Let's see if it's something with permissions..
In Terminal (Applications/Utilities), type
Code:
ls -lias /System/Library/Frameworks/SyncServices.framework/Versions/Current/Resources/SyncServer.app/Contents/Resources/upgradedb
For comparison, on a healthy 10.4 the output would be something like
462336 2008 -rwxr-xr-x 1 root wheel 1026116 Apr 25 2007 /System/Library/Frameworks/SyncServices.framework/Versions/Current/Resources/SyncServer.app/Contents/Resources/upgradedb
At least the owner and permissions should be the same.
What do you get with that command as output?
