Hi Nikolai,

Ah, I was looking for a literal graph :-( Anyway, the graph is 
fascinating. Is horizontal access is by date? The big questionis 
what happened near midnight May 12th. Could you send me the log file (if 
you still have it) for the two days in question? Please don't post it.

If you don't have one from the graph, could you send one with a 
corresponding graph for another period? I need to understand what kind of 
load triggered this. As Matevz says, it may simply be that once the server 
is totally overloaded, things go downhill. In that case, we need to 
recognize the situation much earlier when we have more time to recover.
