Event ID 4612: Internal resources allocated for the queuing of audit messages have been exhausted, leading to the loss of some audits

Windows Event ID Lookup: What Windows event IDs mean: 4625, 4624, 4740, 6008, 41, 7045, 1102 and 3,000 more, with Windows' own message text, the fields and what to check.

Look up a Windows event ID from Event Viewer, a SIEM alert or a log export: what it means, the fields it records, and what to check. Many IDs are used by more than one source (event 41 is both a Kernel-Power crash and a boot error), so every definition is shown, the one people usually mean first. The message text is Windows' own, read from the event providers of Windows 10.0.26200.0, 2026-10-28; the notes are ours, based on Microsoft's security auditing reference.

Message and fields (as Event Viewer shows them) 
Internal resources allocated for the queuing of audit messages have been exhausted, leading to the loss of some audits.

Number of audit messages discarded:	…

This event is generated when audit queues are filled and events must be discarded.  This most commonly occurs when security events are being generated faster than they are being written to disk, or when the auditing system loses connectivity to the event log, such as when the event log service is stopped.
