Hi Gaby,

I guess that very few people have rrdtool setup at your scale ...
so chances for someone coming forward with useful hints may be
rather slim.

Things to look at:

a) try rrdtool 1.5rc2 since this is the latest and greates code

b) go into the cached code and add some debugging output

c) strace/truss may provide some insight in to what rrdcached when
   it seems busy

d) attach gdb and break processing to see where in the source this
   is happening.
