A QRadar user reported the following notification: 38750099 - The accumulator was unable to aggregate all events/flows for this interval When does this message appear?

Question

Options

• AWhen the aggregate data view configuration that is in memory is unable to write data to the
• BWhen the system is unable to accumulate data aggregations within 60 seconds
• CWhen aggregated data views are disabled
• DWhen search results is unable to return over 200 unique objects

• A
  2% (1)
• B
  88% (37)
• C
  2% (1)
• D
  7% (3)

Explanation

Option B is correct because QRadar's accumulator process is responsible for aggregating events and flows into statistical summaries at regular intervals. When the system cannot complete this aggregation within the 60-second window - typically due to high event volume or resource exhaustion - it logs notification 38750099 to alert administrators that data was missed during that interval.

Why the distractors are wrong:

• A is a plausible-sounding distractor but conflates memory configuration writes with the accumulator's timing failure - the issue is a time constraint, not a write failure to disk.
• C is wrong because this message appears precisely when accumulation is running but fails to finish in time; disabled aggregation would produce a different state entirely.
• D is wrong because search result limits are unrelated to the accumulator process - that's a query/reporting layer concern, not a data ingestion/aggregation concern.

Memory tip: Think of the accumulator as a stopwatch sprint - it must finish collecting and aggregating all event/flow data before the 60-second buzzer. If it can't make it in time, QRadar blows the whistle with this notification. The key phrase to lock in: accumulator + 60 seconds = B.
