Hello Jiri,

thanks for the hint. I tried that in the past, but the dump was far too large 
and jhat always crashed. All versions r225 to  r231 allocate millions of small 
objects.
Will see if it helps now.

Gerd

Hi,

in case you have trouble with reproducing the problem, there is java option 
-XX:-HeapDumpOnOutOfMemoryError. Uli can run splitter with this option and then 
send you produced hprof file which you can open in MemoryAnalyzer or jhat. 
There you will see all allocated objects, what takes most memory and in case of 
memory leaks what keeps objects in memory.

Hi,

I want to reproduce the problem, but I don't see a file with 1.9GB at this 
place:  http://140.78.94.22/osm/

Where am I wrong?

Subject: [mkgmap-dev] splitter improvements

I think the memory requirements are more dependent on the data than on the 
splitter version:
I have a self created data set consisting of germany + ~50 kilometers plus the 
data from iceland cut with osmconvert.exe from the europe.osm.pbf from 
geofabrik, which is processed without errors with versions 225, 229, 230 and 
231 using 32-Bit-jvm with Xmx1376m. When i use the about the same sized 1.9 GB 
"germany+"-dataset from here: ( http://140.78.94.22/osm/ ) i can't get thru the 
data without java heap overflow, even with 64-Bit-jvm given Xmx3000m. I think 
there is some kind of endless loop or the like, which causes the algorithm to 
overflow the memory in some circumstances.



Anyway, good work until now! I'm eager to test further splitter versions don't 
requiring the giant overlap-values for routing.
