Ascent 3.0.7

Release Date: 29 September 2026

This patch release makes log ingestion in Flow more reliable, with fixes for stalled connections , Datadog agent checks, large payload handling, duplicate logs and search results during Redis disruption.

Flow

Improvements

• More resilient ingestion when redis is slow or unavailable: Redis operations now have time limits, so a slow or unresponsive Redis can no longer stall ingestion. One slow Redis call no longer holds up other incoming log traffic, and Flash reconnects automatically after a Redis connection drops.

Bug Fixes

• Fixed an issue where HTTP log ingestion (JSON batch, Datadog, and OTLP) could stop accepting new requests under sustained load. When a sender gives up on a request while Flash is busy, Flash now releases that request right away instead of holding it, so other senders are no longer rejected with "too many requests" responses.

• The Datadog log intake now accepts the empty test payload that Datadog agents send when they first connect, so agents no longer report a failed connection check.

• When oversized payload rejection is enabled, payloads larger than the ingest limit now get a "payload too large" (413) response instead of "try again later" (429), so senders stop resending data that will never be accepted.

• Fixed an issue where searches could return partial results, reported as complete, while Redis was unreachable. A brief Redis outage also no longer causes Flash nodes to exit.

• Fixed an issue that could cause duplicate logs when an HTTP ingestion request failed or was cancelled and the sender retried the same data.
