...which has, on closer inspection, its reason in lib/TWiki/Client.pm, lines 253-254:

        if( $time >= $D->{_SESSION_ATIME} + $TWiki::cfg{SessionExpiresAfter} ||
              $D->{_SESSION_ETIME} && $time >= $D->{_SESSION_ETIME} ) {
            unlink( $file ) || die "Failed $!";

It tries to delete expired sessions there. But somehow, at some time, some of the cgisess*-files in my system have been owned not by the webserver, but by my own login user id (maybe I had ran httpd manually for some tests? To be honest, I don't recall). The next day, Apache could not delete these files and TWiki died on every request.

In my opinion TWiki must not die here. It hits some users, at some arbitrary time, and after then "nothing works" until someone finds out what the problem is. A warning is ok, of course, but unfortunately _expireDeadSessions doesn't take parameters and therefore has no easy access to TWikis writeWarning routine.
