SeLinux is disabled on both CentOS servers ...

Same hardware and same server, because all opsys are installed on a ESXi 3.5u4
server with vmware tools ...

Maybe, but why only centos have problems??

So, the problem resides on an ESXi CentOS VM?

I thought you were using a dedicated server though.

If so, what are you using as a NIC?

Sometimes the driver for e1000 gets faulty on RHEL/CentOS VMs, happened to me a couple times, just add a new NIC to solve that.
