WVR_LIVEDUMP_CRITICAL_ERROR
Windows Volume Replication critical error for WVR_LIVEDUMP_CRITICAL_ERROR
WVR_LIVEDUMP_CRITICAL_ERROR is bug check code 0x00000186. This is the high-severity WVR diagnostic bucket. It indicates that the replication component considered the condition critical enough to capture detailed state.
How to read it in a dump
- Use the parameters and WVR component data to distinguish corruption, timeout, service failure, and resource exhaustion.
- Correlate with Storage Replica event IDs and cluster events.
- The live dump should be treated as evidence, not as a complete explanation.
What to check
- Collect both partner logs, cluster logs, and storage diagnostics.
- Check whether the issue followed failover, firmware update, or network/storage outage.
- Escalate with the live dump when WVR component data is needed.

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