Fix: Session “EventLog-AirSpaceChannel” Stopped due to the Following Error: 0xC0000188

This error manifests itself as a system crash (BSOD) and it appears very shady to users as it’s not very common among Windows users. The cause for the error differs from one scenario to another but it’s safe to say that Office tools are to blame.

Session “EventLog-AirSpaceChannel” Stopped due to the Following Error: 0xC0000188

The error is a warning that the performance trace log for the Office 2016 and possible Office 2013, that the log itself, is full or nearly full.  The mistake made by the developers was that they forgot to disable the log before release. Anyway, the problem can be resolved using one of the methods presented below!

What Causes the “Session “EventLog-AirSpaceChannel” Stopped due to the Following Error: 0xC0000188” Problem?

The list of problems which may cause this error is not so large and they are often related to the same log file which has either filled itself up or it’s close to reaching that state. However, there are several ways in which you can deal with this problem, depending on how important you consider the information in the log file is.

  • The file has filled itself up and you have the option to change its property to enable it to overwrite the oldest content in order to keep the same size. This is good for people who don’t consider the log to be important (it’s related to Microsoft Office so it’s not vital to your system).
  • The file is full or almost full and you have the option to change its maximum size in order to enable it to hold large quantities of data. This is great for users who don’t want to lose information which would be lost when overwriting.
  • The third option is to disable the log completely but you will lose this data forever. Office and your system will continue working properly.

Solution 1: Change the Log’s Property to Circular

The log’s current property probably doesn’t allow it to overwrite itself but it will quickly get filled up and it will display this error message on your computer in order to warn you. It would be way better if the log could simply overwrite itself when it gets full.

That’s exactly what the Circular option is there for and we will present two ways how you can change this setting for the AirSpaceChannel log!

  1. Open the Run utility by using the Windows Key + R key combination on your keyboard (press these keys at the same time. Type “compmgmt.msc” in the newly opened box without the quotation marks and click OK in order to open the Services tool.

Solution 2: Increase the Maximum Log Size

There is also another option you could try from the same menu which will effectively increase the log’s size which will enable to keep track of your activity longer. The basic difference between this option and change its property to Circular is that you won’t use any of your data by overwriting (which is done when changing its properties to Circular or Overwrite).
