--- Comment #3 from robert.ayrapet...@gmail.com --- 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. Putting: -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. -- You are receiving this mail because: You are the assignee for the bug.
