Hi!
Have a little problem.
Server gets 2 static IP from datacenter`s network. 1st IP "connected" to ESXi, 2nd - to virtual router (VM on ESXi), that routes traffic to other 2 VM (Win Server 2008, Win Server 2012).
Sometimes ESXi drops connections (so no ping) and nobody cant connect to ESXi Web GUI, but the connection to virtual router doesn`t drop. If i connect via RDP to any WinServer VM and stop it, the connection to ESXi restores after 1-2 minutes.
In vmkernel.log no info about ESXi connection drop. Free RAM - 20 Gb - too a lot for ESXi .
The server connected to network by 1 twisted pair cable, so there is no problem with physical NIC`s interface.
So how to solve this problem?
P.S.
ESXi 6.5 (5310538) is installed on IBM x3550 m3. NIC - QLogic NetXtreme II BCM5709 1000Base-T.
