After an installation of an 11.6.0 hotfix, the datasyncd process may keep restarting during 30 minutes. This is rare, but if it does happen, the system will remain offline during this time, until the state is automatically recovered.


During 30 minutes following the hotfix installation, the system remains offline and does not handle traffic.


An 11.6.0 hotfix is being installed on a system that is already running 11.6.0, and has either ASM or FPS provisioned.


This issue has no workaround at this time.
