ERROR_LOG_CONTAINER_STATE_INVALID

Log service encountered an invalid container state when attempting a requested action.

The native value for ERROR_LOG_CONTAINER_STATE_INVALID is 6642 (0x000019F2). Preserve this result immediately after the failing Windows call because later logging, cleanup, LDAP, RPC, or file operations can replace the last-error value.

This result belongs to Common Log File System (CLFS). A diagnosis of it must connect the condition to the producing API, current state, object identity, and first lower-level diagnostic.

Where the result appears

  • removing a container that is still active.
  • using a container while initialization is incomplete.
  • reopening a container after an interrupted management operation.
  • processing a container whose descriptor disagrees with physical state.

State boundary to prove

This result applies to a CLFS container whose lifecycle state is incompatible with the requested operation and does not by itself prove that the entire server, directory, disk, session, or application is unavailable. The state boundary to prove for this Win32 error is whether the container is in a state that permits the requested add, remove, archive, read, or write transition. Use container state and generation, management operation in progress, and base-log descriptors before and after failure as independent evidence. When evidence for this Win32 error disagrees, preserve timestamps and investigate the transition instead of selecting the most convenient value.

Likely causes

  • the container transition was interrupted.
  • the caller uses stale container information.
  • metadata and file state disagree.
  • a container is pending removal or initialization.
  • concurrent management changed the container generation.

Diagnostic sequence

  1. capture error 6642 immediately at the API boundary and record the operation that was attempted.
  2. identify the exact owner of a CLFS container whose lifecycle state is incompatible with the requested operation, including object generation, server, path, session, replica, or client context.
  3. collect container state and generation before restarting a service or changing configuration.
  4. compare management operation in progress with the documented or observed precondition.
  5. correlate base-log descriptors before and after failure with the owning application log, CLFS-related System events, storage events, and any transaction or recovery trace.
  6. determine whether side effects occurred and verify recovery after changing one responsible condition.

Evidence to collect

  • container state and generation.
  • management operation in progress.
  • base-log descriptors before and after failure.
  • open handles and active clients.
  • recent service termination or storage interruption.

Correlate it with the owning application log, CLFS-related System events, storage events, and any transaction or recovery trace. Keep the first detailed status even when a later wrapper translates it to error 6642; the first status often distinguishes transport, authorization, storage, schema, state, and application-integrity causes that share the same final Win32 result.

Handling, retry, and recovery

The recovery objective is to allow the current transition to finish, reopen the log to obtain current state, validate metadata, and retry only the operation valid for that container state.

Retry it only after the recorded condition changes and completion state is known. Idempotent queries may be repeated after recovery, but mutations require a state check first; backoff cannot repair malformed input, corruption, missing structure, or policy rejection.

Telemetry and support fields

  • record log_container_state_invalid_api for the producing function or management operation.
  • record log_container_state_invalid_target for the file, log, session, replica, object, or server identity.
  • record log_container_state_invalid_state_before and log_container_state_invalid_requested_transition.
  • record log_container_state_invalid_first_status for the earliest lower-level diagnostic.

For support escalation involving it, retain decimal 6642, hexadecimal 0x000019F2, the API, UTC time, target identity, and first subsystem-specific status. Include the smallest reproducible request and evidence that distinguishes this condition from nearby codes. In the context of it, clfs clients can run in user mode or kernel mode, so the same win32 result may be returned through an application wrapper, a service, or a driver-facing management path.

Difference from nearby results

ERROR_LOG_STATE_INVALID concerns the state of the overall log service or log object; this code is specific to one container.

Practical validation scenario

A maintenance tool retries removal using a container identifier captured before another tool extended the log. Re-enumerating the containers reveals a new generation and prevents removal of the active container. The negative test should preserve the responsible condition and reproduce it; the recovery test should change only the identified cause, repeat the same operation, and verify both success and the absence of an unintended partial side effect.

Developer and administrator guidance

Administrators handling it should preserve the complete CLFS set—base log, containers, security metadata, and application checkpoint state—before repair. Developers should never delete or recreate a container merely because its path appears in the error; the owning recovery protocol determines whether that data is still required. Code that exposes it through RPC, JSON, REST, PowerShell, or another protocol should preserve the Win32 domain, decimal 6642, hexadecimal 0x000019F2, and original component diagnostic.
