What causes Fabric Pipeline Error 2500?

The Azure Batch pool ran out of compute resources or nodes were unavailable during job execution. An unhandled exception occurred within the custom script or application running on the Batch node. Network connectivity issues between the Fabric pipeline runtime and the Azure Batch service. The Azure Batch account has reached quota limits for cores, jobs, or pools

How do I fix Fabric Pipeline Error 2500?

Step 1: Navigate to the Azure Portal, open the Azure Batch account, and review the job and task logs for the failed execution to identify the root cause of the unexpected exception.. Step 2: Check the Azure Batch pool status to confirm nodes are healthy, allocated, and not in an error or unusable state.. Step 3: Review the Azure Batch account's quota usage under 'Quotas' in the portal and request a quota increase if core or job limits have been reached.. Step 4: If the failure is caused by an error in a custom script or application, fix the application code, re-upload it to the Batch resource files, and re-run the pipeline.. Step 5: If network issues are suspected, verify that the Batch account's virtual network configuration and firewall rules allow communication from the Fabric pipeline runtime, then retry the pipeline.

Frequently asked questions

How can I view the detailed task-level logs for the failed Azure Batch job?

In the Azure Portal, navigate to your Batch account, select 'Jobs', find the failed job, and drill into the individual tasks. Each task has stdout.txt and stderr.txt output files accessible from the task details pane, which contain the detailed execution logs.

Does Error 2500 always indicate an issue with my custom application code?

Not necessarily. Error 2500 is a general unexpected exception that can be caused by infrastructure issues such as node failures, quota exhaustion, or network problems, as well as application-level errors. Always check both the Batch job logs and the pool/node health before assuming the issue is in your application code.
