If this happened, a full compaction would run on that\r\ngeneration producing just one generation again.  The planner would then\r\nrepeat the plan.\r\n\r\nThis could happen if there were two generations that were both over\r\nthe max TSM file size and the second one happened to be in level 3 or\r\nlower.\r\n\r\nWhen this situation occurs, one cpu is pegged running a full compaction\r\ncontinuously and the disks become very busy basically rewriting the\r\nsame files over and over again.
