Our doc states
The presence of NIS58n messages in the SOLVE SSI log indicates access problems to /var and EZB.NETMGMT.**.
You can review the section on IPSEC Network Management Interface Setup for more information on what is required to configure this feature.
If there are no plans to configure IPSEC at this time, adding parameter
to the SSIPARMS will prevent the error messages from appearing.
