[mkgmap-dev] RAM and mdr Europa ?

Wed Mar 29 19:12:27 BST 2017

I agree, it is not a really solution. But it is the only thing i can do 
with my 10 GB RAM. I will bee happy, if you found a algorythmus, which 
can use -x-split-name-index  and  works with my limited RAM, and avoids 
the OutOfMemory   java heapspace   error. By the way: With a smaller 
inputarea (Easteuropa or Skandinavia), 10 GB RAM is enough to use 
x-split-name-index, no error occurs.

Since  a few months i can not generate the mdr-file for Europa from www.Download.Geofabrik.de<http://www.Download.Geofabrik.de><http://www.Download.Geofabrik.de><http://www.Download.Geofabrik.de> In a first run i generate only all the maptiles. No Problem. in a second i will generate the overview, tdb and mdr. I start java -Xmx9800m -XX:-UseGCOverheadLimit jar mkgmap.jar code-page=1252 -family-id=1901 -x-split-name-index -index  D:\Karten\Europa\*.img.
