05/26/2026, 3:46 PMerror in the log stream — this is a known quirk where Snowflake JDBC driver INFO logs are surfaced at the error log level in Airbyte). [Snowflake Source]
The pattern visible in your logs is:
1. A connection is closed (session closed successfully)
2. A new connection is immediately initialized (~300–360ms to open)
3. This cycle repeats roughly every ~9–10 seconds
This is normal connection pool cycling behavior — the JDBC connection pool is rotating connections. Each session opens and closes successfully, so there are no actual errors in what you've shared.
Things to Note • You are running JDBC driver version 3.20.0, but the latest Snowflake source connector (v1.0.10+) uses JDBC driver 3.23.1. Upgrading to the latest connector version may resolve potential issues and includes fixes like truncating timestamp precision to prevent precision errors. [Snowflake Source Changelog]
• The sync started at 12:10:13 and the connection cycling is still happening at 12:35:47 — a ~25 minute window. If your sync is taking unusually long or failing after this point, there may be a query timeout or data volume issue not visible in the provided logs.
Recommendations 1. Check if the sync ultimately succeeded or failed — navigate to the connection's Job History or Timeline in the Airbyte UI and look for errors after the log snippet you shared. [Browsing Logs]
2. Upgrade the Snowflake source connector to the latest version (1.0.11 as of 2026-05-05) to benefit from bug fixes and the newer JDBC driver.
3. If the sync is hanging, check Snowflake's query history for long-running queries from the airbyte user/role/warehouse.
If you can share logs that include actual error messages or a failure reason, I can help diagnose further. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
