EVENT_TRACING_FATAL_ERROR

ETW fatal tracing failure

EVENT_TRACING_FATAL_ERROR is bug check code 0x0000011D. The built-in table identifies it as EVENT_TRACING_FATAL_ERROR; the useful diagnostic question is what Windows component raised the stop and which invariant failed.

This code belongs to the kernel Event Tracing for Windows path. It is not a normal trace-session warning; Windows stopped because tracing state or a tracing operation became inconsistent enough to be fatal.

How to read the parameters

  • Use the stack and active trace-session state to identify whether the issue involves logger setup, buffers, provider state, or an ETW control operation.
  • The bug check parameters are less useful without the exact build and symbols.
  • High trace volume and low resources can expose tracing bugs but are not automatically the root cause.

What to check in the dump

  • List active ETW sessions and recent tracing tools if the machine can be reproed.
  • Check security, performance, antivirus, and diagnostic agents that create kernel trace sessions.
  • Correlate with low-memory conditions and with drivers that register high-volume providers.
