I think they do, but not in a scientific way.

The system in question has to do always the same task and is running for months
with never dropping below a certain memory boundary.

Then, when asterisk started/stopped/started, memory begins to fade away and is
never getting back to "free", even with asterisk off for days, twoo weeks. Does
this really tell me nothing?

I will.
Now as we have a indication that there is porbably something, I'll go for
deeper investiagtions with a static config.
