Receive Error Code 2803 When Registering or Starting UNAB

Valid on UNIX

Symptom:

I receive the following error message when I try to register a UNAB host in Active Directory or try to start UNAB:

Unable to open nss or create nss cache. Error code 2803.

Solution:

There is not enough memory in the /var directory. To fix this problem, verify that less than 95% of /var is used, and retry the command.
