What causes the memory error in this query?

[divral]

This query https://qlever.cs.uni-freiburg.de/wikidata/C8FPr7 gives me the error "Tried to allocate 3125MB, but only 2959MB were available. Clear the cache or allow more memory for QLever during startup"

I tried removing the /wdt:P279* but it still fails.

The query is (so far, partially) recreating this Wikipedia list: https://en.wikipedia.org/wiki/List_of_tallest_lake_islands

I would really appreciate help with this!

Edit: Never mind, I found the problem myself! Sorry. I wonder if the phenomenon of looking for a problem for ages, then writing a post seeking for help with it, then finding the problem almost instantly, has a name.

Hi, I am wondering how you solved the problem. I had the same error as yours by running their default query without LIMIT "SELECT * WHERE { ?s ?p ?o }". And I also gave a specific grapy in the query such as "PREFIX xxx: http://... SELECT * WHERE { ?s ?p ?o }", but the error message is same.

same here with

SELECT * WHERE { ?s a ?type . }
