Getting same issue with a 1.7.2 vanilla server. Ubuntu 10.04 LTS, dual quad core 2.6, 64 gb ram, 15k sas raid 5 on a 200/200mbps fiber. 2 players connect and I'm getting the "can't keep up" message coming across the console. 1 in 5 times it crashes the server instance and I have to restart it. So it's definitely not ram, disk i/o or connection speed.
Ubuntu 10.04 or 12.04 LTS servers. Tested on both. Problem existed on both but Java 6 installs by default. Shut minecraft servers down.
Ran the following to update to Java 7:
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
Started minecraft servers back up - now running v 1.7.4 mc vanilla. Console has yet to report the error again - been running both servers for approximately 12 hours.
