There is moderate amount of data generated in the CDB after south-bound locking the device in the scale test bed. "sync-to" command is failing with "NXAPI failure :: Connection reset" error to N9K

I have moderate amount of data generated in the CDB after south-bound locking the device. “sync-to” command is failingt with the below error: -

nso:admin@VTC1-45K (config)# request devices device VTS_45K_TOR2 sync-to

result false

Below error from : nso trace log for 1 tor.

Please share the connection settings which can be configured to prevent sync-to failure?

Tried altering the below timeout settings, did not see any difference.

           <connect-timeout>120</connect-timeout>

            <read-timeout>120</read-timeout>

            <write-timeout>120</write-timeout>

Any pointers would be helpful since it is very urgent!

I'd recommend you enable NED tracing for the device:

set device device VTS_45K_TOR2  trace raw

commit

request devices devices VTS_45K_TOR2  disconnect

then retry the sync-to.

Files of interest will be:

logs/ncs-java-vm.log, see if there are any NED errors here

logs/ned-...VTS_45K_TOR2.. , see what the NED/device actually does.
