Cause

This error happens when files in the vsBuilderSessions/VSE_2013 or vseRecording\VSE_2013 get corrupted. 

The vsBuilderSessions creates bundles when you create Virtual Services from the Portal. These bundle contain resources needed for this Virtual Service, for example a WSDL files or RR pairs. There are cached names for these bundles in the vsBuilderSessions catalog. If files are damaged, deleted or changed, the VSE cannot load it, and as a result it throws the error.  They get corrupted if there is an interruption during the recording, like for example a bad endpoint. 

The vseRecording is used when recording a Virtual Service using DevTest Portal, the raw traffic is created in this folder. 

Resolution

Needed to rename these folders and restart the VSE and it came up with no issues:

 

1. DEVTEST_HOME\vsBuilderSessions\VSE_2013

2. DEVTEST_HOME\vseRecording\VSE_2013

3. Delete the mar.tracking files in the DEVTEST_HOME\vseDeploy\VSE_2013 folder
4. Deleted all the logs files.
5. Started VSE service.
