Question Event Viewer Spam Causing PC Stutter - Events 5379, 4624, 4672 -- Security Audits


Dec 26, 2017

Since getting my new PC, I have experienced these instances of noticeable stutter when browsing, gaming, or simply being on the desktop. The best way to describe it is as a very brief but noticeable micro-stutter/micro-freeze, the screen does not flash and audio does not cut out. It lasts for about half a second, but it is very noticeable and annoying, especially when playing games. After spending hours troubleshooting, I have ended up finding the cause. These stutters happen at the exact same logs are generated in the Event Viewer application. These logs are listed under the "Audit Success" column and I currently have about 5000 of these logs just in the last 24 hours. Out of these logs, there are 3 particular Event ID logs that correlate with my stuttering: Event ID: 4624, 4672, and 5379. The 4624 and 4672 occur more frequently than the 5379 and the stutter resulting from them is less severe. The 5379 event however, results in the worst stuttering. This is probably because the 5379 event is logged about 300 times during instances of stutter. Event Viewer shows event 5379 being logged around 300 times at the exact same time interval (For example 300 entries all at 1:00:00PM or 2:37:51PM etc etc).

The events themselves have different descriptions for why they're occuring:

The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on.

The impersonation level field indicates the extent to which a process in the logon session can impersonate.

The authentication information fields provide detailed information about this specific logon request.
  • Logon GUID is a unique identifier that can be used to correlate this event with a KDC event.
  • Transited services indicate which intermediate services have participated in this logon request.
