First I'd review the man page:

DESCRIPTION
       Tracer  determines which applications use outdated files and prints
them. For special kind of
       applications such as services or daemons, it suggests a standard
command to restart it. Detecting
       whether file is outdated or not is based on a simple idea. If
application has loaded in memory any ver‐
       sion of a file which is provided by any package updated since system
was booted up, tracer consider
       this application as outdated.

If that's 100% the case, then it's looking at fairly crude deltas in order
to figure out what needs restarting. And restarting a service doesn't
change tracer's output. Since it's calculating the delta between last boot
and packages updated.

Then anecdotally, I've just updated a system, restarted a service tracer
has identified (as you have), tracer still tells me that it needs
restarting because the calculated delta hasn't changed, despite the service
being restarted?
