You mean cron-like ...not as they arrive?

I am wondering why you are looking into an alternative ....because I am
currently looking into setting something like that up for us.

Well, apache will not be able to send the message to the ring. Up to you
how you deal with that I guess.

I think mod_log_spread has a fall back. But I couldn't get
mod_log_spread to work properly ...and it does not support error logs
anyway.

So I have patched rotatelogs to push the logs into the spread ring.
<<<< Will you be able to share the patch of rotatelogs for me >>>>>>>

I find the spread situation quite bad. No spread4 in debian/ubuntu. No
easy to install mod_log_spread. Not that nice.
There are many things to improve (handling of config errors is
terrible!) but I see no progress. Wondering about the project health
actually.

You mean why the whole ring needs to be defined/configured on each an
every machine participating?
