473410NI-TimeSync only installs examples for the latest supported version of LabVIEW installed on the system.14.5
701793 & 524081In rare instances, the IEEE 1588-2008 time reference can cause 100% CPU usage on Linux RT targets16.0
629071A 1588 time reference might lose synchronization over a 100Mbps link with a heavy network traffic.17.1
Physically disconnecting and reconnecting an Ethernet cable from a cRIO-903x (Sync) or an IC-317x participating in an IEEE 802.1AS protocol can cause synchronization issues. Devices might not be able to synchronize to each other over an IEEE 802.1AS network. A full power cycle of a device eliminates these issues.18.0

If SSH, WIF, WebDAV, or FTP access were enabled prior to the target becoming unreachable, they will still be usable.18.1.1
