Yes. It's not a problem with the Centos box but with the switch. The switch has a flaky power issue that is causing the link indication voltage to either drop below threshold or an overheat issue causing a drop out. I wrote a series of little scripts to test for link every few minutes when I had this issue and restart the networking (network off, unload modules, network start). That would re-init the switch ports but was not a real solution. When I replaced the switch, the problem went away.<br>

I have an interesting issue with a server.<br>
<br>
It is a CentOS 5.1 server running kernel 2.6.18-53.1.4.el5 #1 SMP and every<br>
couple weeks the kernel complains about losing link with a switch switch.<br>
<br>
I access it via the serial console and see no ip address and no link.<br>
Dmesg states the kernel is waiting for link to come up. A reboot does<br>
not seem to solve this problem. Luckily I use intelligent strips and<br>
remotely power cycle the machine. It comes back up and is on the network.<br>
<br>
As anyone seen this behavior before?<br>
<br>
Chris<br>
