On 2026-01-05 at approximately 13:50 UTC, Clari experienced an interruption in the processing of CRM and Activity data into RevDB. Due to database locking issues across multiple clusters, live CRM and Activity updates stalled for some customers, resulting in data freshness delays of roughly 2 to 5 hours. The impact was limited to delayed data updates; the application experience was unaffected, and no customer data was lost.
Clari engineers identified a buildup of long-running, idle-in-transaction database sessions that were causing lock contention. The problematic sessions were terminated, unblocking the affected clusters and allowing CRM and Activity ingestion to resume. To reduce the likelihood of this issue recurring, Clari has implemented changes to prevent idle sessions from accumulating, and we are strengthening monitoring and alerting for database lock behavior to detect and quickly mitigate similar conditions.
