hi,
In our system, we have 3-4 ptp4l services running as master (C1 mode) providing
clock to external device. Our system is synced using ptp support/slave
connected to a BC. From the synced slave/support interface, phc2sys is used to
sync master interface. All the master and slave ptp4l and phc2sys are core
pinned. Once in a while phc offset which is synced into master interface using
phc2sys jumps into 4 digit value. Any suggestion on how to debug this further.

After a while, we are observing NIC interface going down also.
