Hi Thomas,

maybe it helps:
The problem occured while sorting the index entries for streets names. With option  --x-split-name-index
you have one entry for each word in the street name. I think this option can easily dup the number of entries and
aso the required memory for the entries is higher.

We've once tried to fix this partially with Mdr7.patch but it turned out to produce wrong entries in the index.
I'll try again to find a better solution.

In the mean time you may check how your style handles street names. Maybe you often use addlabel or you
add words to the road names ? I've seen styles which add a default name for each unnamed object.

Gerd
