The following alert is raised from the Replica appliance:
A Windows System Error occurred. EventID:1004 Source:W3SVC Description:https:// :443/ 1 AlertDate: <DATE>
Webservice running on Port 443 which the Primary and Replica appliance communicate over momentarily failed or stopped.
If this is a one time Alert this message can be safely ignored. The webservice running on the Replica may have had an issue or stopped, however the appliance will be alerted of this fact and restart the service itself.
If the same alert is raised continuously then a case should be raised with Quest Support supplying the Primary and Replica Logs for the dates the alert was raised along with an export of the Alerts Logs again filtered on the date of the issue.
