Group Cache Refresh cannot schedule an update

Group_Cache_Refresh_cannot_schedule_an_update_5_Rule (Rule)

Knowledge Base article:

Summary

No GC Logon uses the information in the replication schedule to determine when it should attempt to refresh the cache. No GC Logon is able to determine an available window of opportunity to refresh its cache during a period of up to seven days. As a result of a wrong configuration of the replication schedule, no window is available at all within the next week.

This same configuration problem can cause replication to fail. It must be corrected immediately.

Sample Event:

The group membership cache refresh task was unable to find the next available time slot of connectivity to the following site. Site: %1 This operation will be tried again at the following interval. Interval (hours):%n%2
