Mastership continously changing in onos 2.7.0 for netconf devices

[Anurag Chadha]

Hi All,

We updated our code to use onos 2.7.0 tagged code from 2.5.2 tagged code and we are observing netconf connection going down due to frequent mastership changes with below logs for devices in the system:

WARN  [DeviceManager] Failed to assert role onto device netconf:192.168.251.7:830. requested=MASTER, no response
INFO  [DeviceManager] Successfully relinquished mastership for netconf:192.168.251.7:830. Requesting new role

Mastership of devices is continously changing due to which there is no stability in netconf connection with the devices. Can anyone please help us understand the changes done in onos 2.7.0 due to which this issue is being observed and is the issue related to netconf protocol only ??

Has anyone else observe this issue with netconf devices ?

Regards,
Anurag
