I'll try this nevertheless.

I'll have to rely on any kind 3'rd party person with a mac then, anyone?

It runs httpd-2.0.50-2.1

Well, I know there is the buffer and cache. But this is actual used
memory as calculated by:
let mem_used=$mem_total-$mem_free-$mem_buffers-$mem_cached
Those are extraced from /proc/meminfo

My script records a steep climb from 10% used up to 80% in just ~30sec,
then the logfile goes silent. The log is written every 10sec.
It also gains ~600-900 in load during that same time.

Whatever does it is doing it FAST.
