The GCInspector's start() method , In this method , StorageService.scheduledTasks.scheduleWithFixedDelay(t, INTERVAL_IN_MS, INTERVAL_IN_MS, TimeUnit.MILLISECONDS); t is Runnable t and it's run method is logIntervalGCStats. According to this code segment , the logIntervalGCStats should be run every second. But the log of cassandra shows the logIntervalGCStats didn't run every second,it's disorder . How this happened? -- Best regards, Ivy Tang
