Running `community_detection_online.set()` causes Memgraph to crash

[katarinasupe]

I ran community_detection_online.set() on a large dataset (around 200k nodes, 1M relationship) on a running Memgraph instance with 24 GB RAM. Memory spiked and caused Memgraph to crash. It would be great if, in that case, Memgraph does not crash, but the transaction is stopped instead.
