WORKER_THREAD_TEST_CONDITION
Kernel worker-thread diagnostic condition for WORKER_THREAD_TEST_CONDITION
WORKER_THREAD_TEST_CONDITION is bug check code 0x00000163. This code is tied to kernel worker-thread test or diagnostic paths. It is useful when a checked, instrumented, or diagnostic kernel path deliberately validates worker-thread behavior rather than when an application thread simply becomes busy.
How to read it in a dump for WORKER_THREAD_TEST_CONDITION
- Look for worker-thread, delayed-work, or executive worker queue frames in the dump.
- Check whether the machine was running verifier, test signing, internal diagnostics, or stress tooling.
- The queued work item and owning driver matter more than the constant name.
What to check for WORKER_THREAD_TEST_CONDITION
- Inspect worker queue state and the module that queued the current work item.
- Disable lab-only stress or verifier settings only after collecting the dump.
- Check for drivers that block worker threads or recursively queue work without progress.

Dump evidence for WORKER_THREAD_TEST_CONDITION
For WORKER_THREAD_TEST_CONDITION, preserve the complete dump, the four bug-check parameters, the exact Windows build, loaded-module list, and the event timeline immediately before the stop. AllStat summarizes the condition as “WORKER_THREAD_TEST_CONDITION”; that sentence identifies the failure class, while the parameters and stack determine which object, driver, processor, or subsystem instance was involved.
Analysis order for WORKER_THREAD_TEST_CONDITION
- Run WinDbg
!analyze -v, then inspect the documented meaning of each WORKER_THREAD_TEST_CONDITION parameter instead of relying only on the probably-caused-by line. - For WORKER_THREAD_TEST_CONDITION, find the earliest abnormal event: driver update, firmware change, device reset, storage error, verifier report, resource exhaustion, or application hang connected with worker / thread / test / condition.
- For WORKER_THREAD_TEST_CONDITION, keep third-party filter, security, storage, graphics, and virtualization drivers in the module inventory; removing evidence before dump analysis can obscure the responsible path.
Do not repeatedly reboot a machine affected by WORKER_THREAD_TEST_CONDITION before collecting the dump and event logs. For WORKER_THREAD_TEST_CONDITION, recovery actions should follow the component identified by the stack and parameters, not merely the symbolic stop-code name.
