Hi,
I have one Dell force 10 s4820t and few servers are connected to it with 10Gig cards. Model of card is Intel Corporation Ethernet Controller 10-Gigabit X540-AT2.
In every approx half an hour connection to all server goes away. I can see the logs that all ports goes down and comes up, downtime is of about 1sec or less then 1sec. but because of this down time my cluster stops and some files get corrupted.
Connection to all server goes down at once.. below are logs from my switch for ports
