This is the standard Macintosh error procNotFound. It is usually a response
when trying to send an AppleEvent to a non-existant target (or, more
technically, when the mach port for AppleEvents for that target cannot be
found). This would usually be generated by the toolbox, but we generate that
error in two cases: (1) if we cannot find the Alerts Daemon (usually found
in the Office subfolder) to launch to show the "toasts" (notifications that
new mail has been received), (2) if we're trying to open a document and
cannot find the Finder application (this is usually when you're opening
Entourage on a system that is too old, so probably not your case), and (3)
in some generic process code that tracks whether other processes (e.g., the
Database Daemon) are running.
Is the Alerts Daemon where it should be, and can you launch it manually?
(You'll see it in the Activity Monitor.)
Is the Database Daemon where it should be, and can you launch it manually?
(Again, you'll see it in the Activity Monitor -- if you don't have any
future reminders set, though, it will quit after 30s.)
Was this a transient error, or do you see it often?
