CWPKI0714I: The certificate expiration monitor has recently run and discovered that the certificates, which are listed in associated messages, will be replaced within the next 90 days. This replacement is based on the configured policy to automatically replace expiring self-signed certificates 60 days prior to expiration. This notification is informs you that problems might arise when the certificates are automatically replaced.

CWPKI0715I: In some cases, automatically replacing certificates can cause outages for Web server plug-ins operating on unmanaged nodes. In such a situation, the plug-in will be unable to contact the application servers over HTTPS because it will be using signers for certificates that have been replaced by the automatic replacement process. To prevent what may be and serious outage you should act before the scheduled replacement date and replace the expiring certificates and update the plug-in kdb to use the new signers.
