Time Machine slowing down entire system!

Hi all,

It has taken a while to pinpoint why my system has been so flaky lately. I've been having issues where my entire system would slow down and if I try to reboot, it would just hang requiring a force shutdown. Further, at times even clicking on the dock would hang the dock and issuing a killall Dock command would not restore it. I even performed an erase and install on my system and started from scratch only to find that the issue persists. After some investigative work I've found that the issue is related to time machine. The only time the system experiences this behavior is when time machine is performing a backup. It sits at "Preparing..." indefinitely. I am backing up to an AirPort disk along with two other computers, which don't experience any issues. I have also tried deleting the sparsebundle and starting with a fresh backup, however the problem reappears in a few days. Here is the console log when my system goes into this weird mode:

5/4/09 May 4 - 10:13:50 PM kernel AFP_VFS afpfs_DoReconnect: get the reconnect token

This repeats forever. Stopping the backup will not work. The only solution to get my system back is a force shutdown. This issue is very frustrating. I'm hoping someone knows what is wrong or can lead me in the right direction.

Thanks!

P.S. I've disabled Time Machine for now and the system is running flawless.

Anyone?

When all else fails here, call Apple support!!!

I'm afraid this is a very unique issue and they will just have me run through basic steps like reformatting the TM drive, reinstalling OS x, all of which I've done already.

I performed an experiment today and unplugged the ethernet cord on my iMac and connected via AirPort. When I did this the backup performed just fine and did not hang the system. However, of my other 3 macs, 2 are hardwired and do not experience this problem.

Could there be a potential hardware issue with the network card on my iMac?

Perhaps you could call Apple support and they could help, what about the CAT5 cable, perhaps that is the issue?

Nevermind it finally failed on the airport as well
