[plug] apache help

[Jon Miller]

I've noticed that a clients log has over 50 incidents of the following:
www-data 27940  0.0  0.3 62808 3012 ?        SN   Dec20   0:00  \_ /usr/sbin/apache2 -k start -DSSL.
Issuing "apache2 -k stop" stops the program, but I need to find out where it starts from in the first place and what does -DSSL mean.
They do not use (to my knowledge) apache.
This is a Debian server

Thanks
