Hi,
Today I noticed that some of my network traffic graphs had stopped working.
I checked ifconfig and found that the bytes counter had stopped incrementing
for the network device. As you can see in this ifconfig dump, the TX bytes
is (2^32)-1, and is stuck there.
eth0 Link encap:Ethernet HWaddr 00:02:55:B7:18:8B
inet addr:193.201.200.181 Bcast:193.201.200.255

RX bytes:1320960190 (1259.7 Mb) TX bytes:4294967295 (4095.9 Mb)
Interrupt:7
The network card is a Broadcom 10/100/1000 device. The server is an IBM
X305, and the kernel is a rebuilt 2.4.19 with no fancy stuff, just the basic
drivers needed. Here is the relevant excerpt from /proc/pci:
Bus 2, device 4, function 0:
Ethernet controller: BROADCOM Corporation NetXtreme BCM5703X Gigabit
Ethernet (rev 2).
IRQ 7.
Master Capable. Latency=64. Min Gnt=64.
Non-prefetchable 64 bit memory at 0xed6f0000 [0xed6fffff].
Bus 2, device 5, function 0:
Ethernet controller: BROADCOM Corporation NetXtreme BCM5703X Gigabit
Ethernet (#2) (rev 2).
IRQ 5.
Master Capable. Latency=64. Min Gnt=64.
Non-prefetchable 64 bit memory at 0xed4f0000 [0xed4fffff].
Can anyone help with this issue? Is this a known bug or is it quite
unexpected these days to see the notorious counter overflow? Does anyone
know of a fix?
Thanks
Michael
