Just to follow-up, I don't have this server anymore, but my last reply to DC
technicians after they've completely replaced the whole server was:

UPD: so the issue has happened again right after server\cables were replaced,
so seems it's a NIC driver.
-rxcsum -rxcsum6 -txcsum -txcsum6 -lro -tso -vlanhwtso
to interface definition in rc.conf seems resolved the issue permanently.

So Yif, try that approach or better move to another NIC.
