Hi Rob,
I started reading about flock() out of interest.
I guess you've probably looked at the user notes:
http://uk.php.net/flock
It seems no-one can agree on anything to do with flock().
Would it be suitable to use a mysql database for an error log?
I'm assuming these problems wouldn't occur with a DB.
Regards, Bob E.
