Ethernet Frame Errors on IFconfig

[C4talyst]

Today a machine used as a mailserver with a dozen or so domains started kicking out interface errors:

[root@host root]# ifconfig -a
eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:xxx.xxx.xxx.xxxBcast:xxx.xxx.xxx.xxxMask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:590252419 errors:396728 dropped:0 overruns:5 frame:396728
          TX packets:43282320 errors:0 dropped:0 overruns:5 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:945598683 (901.7 Mb)  TX bytes:734343226 (700.3 Mb)
          Interrupt:10 Base address:0xe000 Memory:d6202000-d6202038

After searching for similar problems for a couple hours I replaced the cable and what was a steady flow of errors went to a trickle. I'm a little confused about the results of swapping the cable. This system did not have interface errors before today. Is it possible I swapped in another questionable cable, or is there some other issue at play here?

Thanks!

I'd try changing the network card and if that doesn't stop the framing errors, I'd look at the rest of the network for hardware problems (router/hub it's plugged into?).
