WinSyslog Event ID 11152: A queued event has an unsupported information-unit type#

Answer#

The product could not reconstruct an event from serialized queue data because its stored information-unit type is not recognized. That queued event is discarded.

Event details#

  • Event ID: 11152

  • Severity: Error

  • Component: Event reconstruction

  • Windows Event Log source: AdisconWinSyslog

  • Available since: 26.07

  • Message pattern: A queued event contains invalid information-unit type {type_id}; the event was discarded.

Possible causes#

  • Queue data was written by an incompatible product version.

  • The serialized event or queue file is damaged.

  • An unsupported component produced the information-unit type.

Immediate checks#

  1. Preserve the affected queue data and record the type identifier before changing files.

  2. Confirm whether the queue was carried across a product downgrade, cross-product copy, or incompatible upgrade.

  3. Collect configuration and debug evidence and contact support before deleting or replacing queue data.

Detailed procedures#

Verify the result#

Confirm that newly queued and replayed controlled events are reconstructed successfully without Event ID 11152.

Evidence to collect#

  • The complete Windows Application Event Log entry and neighboring product events from the same time window.

  • The exact product version, affected service or action name, and event timestamp with time zone.

  • The affected configuration object and a bounded debug log covering one controlled reproduction.

  • Remove passwords, tokens, license data, private keys, message payloads, personal data, and customer-identifying names, addresses, hostnames, domains, and network addresses before sharing evidence.

Escalation#

No safe general self-service repair is available for this event. Follow the escalation evidence procedure above and contact Adiscon Support.
