Lync 2013 Server Running Out of Disk Space

Problem:

On the Lync 2013 Application Server you will notice that the C:\ space slowly depletes and you cannot understand why.

There is a hidden Windows Fabric folder that is accumulating log files. Here is the location:

• C:\ProgramData\Windows Fabric\Fabric\log\Traces
• In this folder you will have .etl files.

The problem here is each time the log file reaches 128MB it creates a new one.

Solution:

Open up an elevated command prompt and run the following:

• Logman update trace FabricLeaseLayerTraces -f bincirc --cnf

What does this command do? This will change the logging to circular.

 –cnf is used to “create a new file when the log size has been exceeded”.
