I also thought that program termination released locks, that's what puzzles me most.
My apologies, but the lock in my code is actually LOCK_EX (I copied the code directly from the book instead of from my program).
Unfortunately I've never witnessed the last run of the program before it stops, so I've no idea how it dies. I'm just assuming that it's the lockfile because as soon as I delete it all other programs run freely again. On average it occurs once every 2 days.
I'm going to try coding in an END block and see if that alleviates the problem...... time will tell.

Thanks everyone for your replies.
