Question about INN 2.2.1-1

[Aladdin]

Hello inn-workers,

      I have a default RedHat 6.1 installation with INN 2.2.1-1
      installed. When I do the following: "innd stop" I can see the
      following entries in logfiles:

errlog
INND exiting because of signal

news.crit
Jan 22 14:22:48 debesiukas innd: SERVER shutdown received signal 15

    I did not saw these entries in my previous RedHat installation so
    I'm asking: is that normal thing or there is some kind of
    workaround? Thanks in advance.
