Debian 7.4 64bit Network Connectivity Issue

Postby caesar305 » 2015-10-16 15:00

Hello,

We are having an issue where our network connection is dropping on our server. Everything was working for about a month without issues then suddenly we expereinced a network outage.
Here is what I found in our logs. Rebooting the machine was the only way to have everything come up.

We have the same exact server, running the same exact debian version for over a year with no issues. Any suggestions?
