Greetings,
I have an interesting access issue with my Reviewboard instance.
I have a dedicated VM running reviewboard 1.5.4.
The Problem:
Every now and again users have issues using the system and I get Admin
alert emails with the details below. The load on the machine goes up
to approximate 4 (single processor).. more observations below.

While trying to restart apache (and this is the wierd bit), patch
appears to get started and open 'port 80' (yeah, I don't understand
this either).

Question 1: Why does 'patch' have port 80 open? ( I have some
thoughts, but it requires more knowledge on how
reviewboard calls patch ).
Question 2: Is this what would cause issues accessing the apache
server? (It certainly doesn't allow the apache server to restart.)
Cheers,
Paul
