    - Post the error message as it appears in the logs of the 3750 switch stack and also as to how it is reported in the logs of the Unifi swatch  ; 

                 even better configure a central syslog server on the 3750 switch stack and the  Unifi switch (too).
                Then checkout the logs from the devices on the syslog server when this event happens,
