Thank you Kurt - that makes sense.
Will certainly reduce it to 1024.
Greatly appreciate your quick reply.
Thanks,

Looks like you've hit a bug (not the first time I've seen this in relation to
C* configs). compaction_large_partition_warning_threshold_mb resolves to an
int, and in the codebase is represented in bytes. 4096 * 1024 * 1024 and you've
got some serious overflow. Granted, you should have this warning set
considerably lower than 4096MB anyway. Try set it to 1024MB. Looks like this
affects multiple versions so I'll create a JIRA/patch soon.
Relevant code:
public static int getCompactionLargePartitionWarningThreshold() { return
conf.compaction_large_partition_warning_threshold_mb * 1024 * 1024; }
