Hi,

I'm referring to a query like this, based on the Wikidata cats example:

SELECT ?item

WHERE

{

?item wdt:P31 wd:Q146 .

?crash rdfs:label ?_crashLabel

}

on my local Blazegraph, I can see that it uses up all the CPU cores and goes up in RAM, and eventually kills the query with:

Caused by: com.bigdata.rwstore.sector.MemoryManagerOutOfMemory

at com.bigdata.rwstore.sector.MemoryManager.getSectorFromFreeList(MemoryManager.java:646)

Could Blazegraph prevent this query from even starting?

Thanks!

Cheers

Miguel
