After providing all the details in the Recording window, running on Portal, the Start Recording button is selected.
This button acts like it is in a loading state and goes back to the initial status - "Start Recording".
It is not possible to record a virtual service using the VSE Recorder in the Portal.
For every recording session that is started in the Portal, a new folder is created under DevTest_HOME/vseRecording/<VSEName>_2013 folder.
It looks like something was corrupted inside this folder, not allowing the VSE Recorder to start in the Portal.
We have experienced issues with the vseRecording folder content getting corrupted when the VSE server runs out of disk space and if the VSE goes down unexpectedly while the recording process, via Portal, was happening.
Supported DevTest versions.
Stop VSE component.
Rename the folder DevTest_HOME/vseRecording/<VSEName>_2013 to DevTest_HOME/vseRecording/<VSEName>_2013_old.
Start VSE component.
When the VSE starts a new VSE_2013 folder is created.
The previous recording sessions won't be available in the Portal - under Virtual Service via Recording/List.
