Please sync up with netops to replace its optics one one side and clear the counters clear interfaces statistics xe-4/0/0
Then monitor to verify if the issue is fixed.
If not, please repeat with the other side.

Re-opening as we're seeing errors again (at a lower rate, but errors nonetheless)
https://librenms.wikimedia.org/graphs/to=1536910800/id=6828/type=port_errors/from=1536219600/ were the previous ones
https://librenms.wikimedia.org/graphs/to=1539762300/id=6828/type=port_errors/from=1539157500/ are the new less frequent errors
Need to wait longer between optics replacement as the errors are less frequent.
