[bappppp]

Hello,

Thank for your dev, your project is very usefull.

Expected Behavior

No error :)

Current Behavior

Error with the tile 131/90 : "'Exception in thread "pool-2-thread-1" java.lang.OutOfMemoryError: GC overhead limit exceeded''"

Steps to Reproduce the Issue

My goal is to add some tags (drinking_water, bakery, picnic_table, toilets, & camp_site) directly in my bolt v2 (for a France's map). So i customize tags-to-keep.json and tag-wahoo.xml.
Next i launch the program : "python -m wahoomc cli -xy 131/90 -tag tag-wahoo.xml -v"
After some processing, i've an error.

Context

• OS/Platform: Windows

Hello,

Ok, my knowledge is too limited to understand. But i can fix this issue by lauching the command "set JAVACMD_OPTIONS=-server -Xmx2G" before your tool.

Thanks again for your tool. He is very usefull !

Hi @bappppp,
nice that you found the solution by yourself! I didn't know that one can launch this command prior to execution of wahooMapsCreator.
I added this possibility to the FAQ: https://github.com/treee111/wahooMapsCreator/blob/develop/docs/FAQ.md#i-have-a-java-error-java-heap-space---out-of-memory

In 3. I have described a permanent soution, in both ways you could as well have -Xmx3G to allocate even more memory for java.

Thanks for your kind words, I am happy you use the tool! 👍
