RESERVE_QUEUE_OVERFLOW
Kernel reserve queue overflow for RESERVE_QUEUE_OVERFLOW
RESERVE_QUEUE_OVERFLOW is bug check code 0x000000FF. This bug check indicates that an internal reserved queue grew beyond the expected limit. It is most useful when the stack identifies the subsystem that owns the queue, such as memory manager, I/O, networking, or a legacy driver path.
How to read it in a dump for RESERVE_QUEUE_OVERFLOW
- The queue owner is more important than the symbolic name.
- Look for a producer that continues queuing while the consumer is blocked or failing.
- Resource exhaustion can be the result, not the root cause.
What to check for RESERVE_QUEUE_OVERFLOW
- Inspect the owning subsystem and queue entries in the dump.
- Check for stuck worker threads, blocked DPCs, or failed I/O completion.
- Use performance and event logs to correlate resource pressure before the crash.

Dump evidence for RESERVE_QUEUE_OVERFLOW
For RESERVE_QUEUE_OVERFLOW, 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 “RESERVE_QUEUE_OVERFLOW”; that sentence identifies the failure class, while the parameters and stack determine which object, driver, processor, or subsystem instance was involved.
Analysis order for RESERVE_QUEUE_OVERFLOW
- Run WinDbg
!analyze -v, then inspect the documented meaning of each RESERVE_QUEUE_OVERFLOW parameter instead of relying only on the probably-caused-by line. - For RESERVE_QUEUE_OVERFLOW, find the earliest abnormal event: driver update, firmware change, device reset, storage error, verifier report, resource exhaustion, or application hang connected with reserve / queue / overflow.
- For RESERVE_QUEUE_OVERFLOW, 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 RESERVE_QUEUE_OVERFLOW before collecting the dump and event logs. For RESERVE_QUEUE_OVERFLOW, recovery actions should follow the component identified by the stack and parameters, not merely the symbolic stop-code name.
