To which files? Any of them?

Possibly. How are you restarting it?

My guess is that your restart process somehow rotates the file(s) you
are expecting out of the way (or deletes them) but the new process has
already started logging to them, so it looks like nothing is happening.

On *NIX systems, processes will happily continue to write to deleted
files and the data basically never makes it to the disk. (Actually, it
does make it to the disk, but no other process can reasonably read
that data).

Another possibility is that Tomcat is basically not starting, due to
e.g. a port conflict. When this happens, Tomcat logs a small amount
and shuts down. But in that case, you'd be saying "Tomcat does not
start up again" so that's probably not the case, here.
