packet_write_wait during SSH connection (Unexplained SSH disconnection)

Hi guys,

I am trying to debug an odd SSH disconnection issue. I am logging in from my laptop to a server (which is a vmware vm) and every few minutes or even within one minute, I am thrown out of the SSH session. The message that appears with -vvvv is:

packet_write_wait: Connection to <host> port 22: Broken pipe

Now, there could be problems outside the scope of networking, such as duplicate MAC address/IP address assigned to this vm. But without bugging the vm folks, is there a way that I can at least point out where the problem lies?

1) I must mention that I am seeing heavy packet losses in the vm. The RX drop counter is totally off the chart.

2) The kernel module in use is vmxnet3. Kernel is 3.10.0-327.el7.x86_64.

3) In my client side tcpdump (from my laptop), I am seeing that a RST packet is being sent from the vm (apparently a zero window packet). Could that be problem?
