this blocks successfully with two users...does it have any issues with 6 or more users?

If it blocks for two users, it should block just fine for more, but exactly that may be the problem - depending on how frequently you need access, your processes might suffer from starvation. If this is a concern, you may want to consider different strategies. I see you are working in a directory called "logs" - what do you need the lock file for?
