Description (partial)

Basic Description and Symptom:

This error message is seen when the IPSec verifier function returns an
error (generic "unknown error") when its communication fails with the ipsec control process.
IPsec should return an error message that explains the cause.


This happened due to a bug in sysdb component (CSCee16838) that has since
been fixed. So, this should not be seen.
