Environment

DLP 15.x, 16.x

Resolution

The Enforce server initialization is delayed due to a tomcat error. Check the following:

- Recycle the Oracle services, then recycle the Enforce services and attempt to login to the console again.
- Check if there is an IIS server running on the Enforce server, if so, stop it.
- Check if there are any lock files (*.lck) under DLP directories. If so, delete them and recycle the Enforce services.
- Try stopping all non-essential services on the the Enforce Windows server and restart the Symantec DLP Manager service.
- Look at the system event logs and see if there are system errors that are causing tomcat to behave badly.
- Check whether there are recent Java updates on the Enforce box.
- Make sure AV exclusions are in place.
