What does BSOD 394 (SILO_CORRUPT) mean?

SILO_CORRUPT

Kernel silo/container state corruption for SILO_CORRUPT

SILO_CORRUPT is bug check code 0x0000018A. Windows uses silo-style isolation for container and server-silo scenarios. This bug check points at corruption in that isolation state, such as inconsistent object namespace, job, token, or per-silo kernel data.

How to read it in a dump

• Identify the silo, container, or isolated service context in the dump.
• Object namespace, job object, token, and process lifetime evidence are important.
• The failing process may be a victim of corrupted per-silo state.

What to check

• Check container runtime, Host Compute Service, and recent isolation-related updates.
• Inspect the process and job hierarchy in WinDbg.
• Look for drivers or filters that do not correctly handle server silo contexts.

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 silo / corrupt.
• 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.
