Hi Sujay,

I am not sure about the root cause (it might be a JanusGraph bug or a Datastax CQL driver bug), but you could try the JanusGraph 0.6.0 version and disable the `storage.cql.executor-service.enabled` option (https://docs.janusgraph.org/configs/configuration-reference/#storagecqlexecutor-service), which does not use an internal thread pool for CQLStoreManager as opposed to 0.5.3. If the problem still exists, I would argue it is more likely to be a bug with the Datastax CQL driver.

Best,
