Elevated GIT/Application Builder Errors

Delta generation service experienced degraded performance from ~0900 UTC Feb 4 to ~1700 UTC Feb 5, 2026, due to 32-bit address space limitations affecting large image delta processing.

Impact:

• Delta generation timeout rate increased significantly for large container images
• Users experienced slower image deployments and potential timeouts
• No data loss or security impact

Root Cause: Worker auto-discovery began routing some large delta generation tasks to 32-bit Docker sockets, causing memory constraint failures.

Resolution: Corrected worker selection routing to only use 64-bit sockets for delta generation.

Follow-up Actions:

• Improve monitoring of delta generation performance and failure rates
• Add alerting for threshold violations to detect similar issues faster

We apologize for the service interruption and any inconvenience this caused to your deployments. We are committed to improving our monitoring and alerting to prevent similar issues in the future.
