[SOLVED] some apache2 processes run as root?

[Tuvok]

In /etc/httpd.conf there are the following settings:
User apache
Group apache

ps tells that there are 2 root and 5 non-root processes.
And also the java-bridge process is running as root:

Can anyone confirm the same behavior? What are the reasons?
