qlever index gets stuck for Wikidata

[s-jse]

Hi,

I'm using qlever-control to host a local version of Wikidata. I'm using the latest version of wikidata Qlever file (updated yesterday).
I have successfully run qlever setup-config wikidata and qlever get-data. But the next command qlever index gets stuck after about an hour.
Here is the last line of the log:

...
INFO: Triples parsed: 18,250,000,000 [average speed [averag3.4 M/s, last batch 3.9 M/s, fastest 4.8 M/s, slowest 1.0 M/s]

I ctrl+c'd the script after 7 hours of it being stuck. Then running qlever start logs the following in wikidata.server-log.txt, indicating that indexing wasn't done properly:
