Issue/Introduction

We have recently upgraded to DevTest 10.6. and Catalog service. But catalog service is not running, it is stopping after few minutes.  

Cause

"Web server failed to start. Port 51110 was already in use".  VS Catalog runs on port 51110.

Could see there was an application already running on port 51110:

The PID showing was connected to the Portal, which seemed odd.  This might have been related to a security scan being run.

Environment

Release : 10.6

Component : CA Service Virtualization

Resolution

Doing normal housecleaning resolved issue:

1. Brought down all DevTest components.
2. Cleaned out all log files. (lisatmp)
3. Started all services.
