Thank you Bill - this is what I had in mind - whether appending to a
large file will not be an issue? It is currently about 145MB. By the end
of month it will surely be around 300MB.

Yes, I am compressing them. Load is not an issue yet but I want to
optimize things that can be optimized. So I guess, rotate more often? I 
like the idea of having one monthly log because it is then processed by 
web stat software so it is easier to submit one than a couple of them.

Thanks!
