Thank you all again for your good and detailed answer.
I will combine all of them to try to build a better environment.
*Just a last question...*
/I don't remember exactly when I needed to increase the java heap.../
/but is it possible that this was for the DataImport.../
*Would the DIH work if it cannot "load" the temporary index into the
java heap in the full-index mode?*
I thought that's why I needed to increase this value...but I might be
confused!
kind regards,
Bastien

I don't actually know whether permgen is allocated from the heap, or *in
addition* to the heap. Your current allocated heap size is 20GB, which
means that at most Java is taking up 30GB, but it might be just 20GB.
The other 30-40GB is used by the operating system -- for disk caching
(the page cache). It's perfectly normal for physical memory to be
almost completely maxed out. The physical memory graph is nearly
useless for troubleshooting.
