PICOF Integration Fails with Java Socket Timeout or Connection Reset
What it means
The PICOF (Payroll Interface) integration is timing out or having its connection reset while it tries to pull payroll interface data for a run. The web service call takes too long to respond and the client-side timeout fires before Workday finishes building the response.
Troubleshooting
- Check the integration event's error detail for the exact exception: SocketTimeoutException means the client gave up waiting, SocketException: Connection reset means the connection was dropped mid-response, both point to a slow-running request rather than a data validation problem.
- Compare the population size and date range of the failing run against a run that succeeded; a sudden spike in worker count, or a Get Payroll Group Populous Data call spanning an unusually wide date range, is a common trigger.
- Check whether a contingent worker or worker type outside the integration's intended scope is present in the pay group; some PICOF configurations are not built to handle contingent workers and can hang or error when one of these workers is transformed.
- Re-run the same integration event manually during low system load to see if it succeeds, since transient load on the tenant contributes to timeouts.
- If three or more concurrent inbound PICOF/Studio integrations hit the same Put web service around the same scheduled time, stagger their schedules and retest one at a time to isolate whether contention is the cause.
Re-run or resubmit the same PICOF integration event outside of any other concurrently scheduled integration windows; a clean re-run often succeeds once contention or a transient slow response clears.
Narrow the integration's worker population filter to explicitly exclude worker types (e.g. contingent workers) it isn't designed to process, and stagger overlapping scheduled integration runs so they don't compete for the same web service endpoint at the same time.
