Actually, I presume that logrotate compresses the file after it rolls it, so if
this did take a while would it have any adverse effect on the system?

Thanks Louis,
I'll add that in now. Thanks.
I would like to roll this log by hand though if at all possible as I'm not sure
how long the compression will take as part of logrotate.
I don't have 17GB spare on the server unfortunately.
lsof /usr/local/pf/logs/httpd.portal.catalyst shows me that httpd is using the
file (as expected). So, am I able to rename the current
/usr/local/pf/logs/httpd.portal.catalyst file, create a new one, and restart
the httpd service in order to get apache to use the new file? I would like to
do this with as little downtime to the end users as possible of course.
Cheers,
Andi

None at all.
It should be there. If it isn't you ought to add it.
I can only imagine this will take a while to compress this huge file, so if I
create an empty file by hand and move the old one out to do by hand will
PacketFence just continue to use the new empty file?
No. if you do that the processes will keep writing to the old file regardless
of it's name.
Remember that what matters to a process is a file descriptor, not a file name.
So if you do that you should restart any process that has an open file
descriptor to that file (find out with lsof).
Alternatively, if you have a spare 17Gb lying around you could add it to the
log rotation with the copytruncate option.
That will copy the contents of the file and then truncate it, neatly solving
the file descriptor issue.
