If there are hundreds of partitions and changes to the configuration are made via the GUI, the configuration save can hang. When the configuration save hangs, all subsequent configuration saves will not complete.


Subsequent attempts to save the configuration will not complete.


-- Hundreds of partitions with objects contained in them. -- Changing config via the GUI.


For this scenario, syscalld is the process that created the tmsh process to save the config where the tmsh process hangs. A restart of syscalld using bigstart restart syscalld will kill the hung syscalld and tmsh processes and restore services.
