Hi Julian,

The logic is in /etc/init.d/apache2 from around line 198. What does "pidof /usr/sbin/apache2" give you please, and what is its exit status? If it does provide some pids, then what does ps report against them? And what files and what contents are in /var/run/apache2/?

[Julian Edwards (julian-edwards)]

Hey Robie,

As you can see in the description, there was nothing in /var/run/apache2 at all.

However as is typical in these situations, it's stopped happening :( I'll leave this incomplete and comment back again if I see it re-occur.
