I was losing ssh connection to my server occasionally and for short periods of time. When I checked var/log/messages I saw the following errors, why could this happen and how can I fix it?

OS: Oracle Linux Server release 6.6

You have dhcp going to two interfaces? Are they on the same subnet? Do they have the same default gateway?

I checked. I gave fixed ip but NetworkManager was active, I turned it off. Secondly, the em1 network interface was trying to get automatic ip, I also turned it off.

Now the log does not show the same error. I will follow a little more and edit the topic accordingly
