linux 运行一段时间后，网络中断

我有一台Linux机器,运行一个中间业务服务(每天3-4万业务)，运行一段时间后就ping 不通,但只要到主机上ping其它主机，又通了，这是为什么？
ifconfig -a:
eth0 Link encap:Ethernet HWaddr 00:50:04:FC:00:75
inet addr:10.137.9.73 Bcast:10.137.9.255 Mask:255.255.255.0

请大家注意ifconfig -a中的
RX packets:2320541 errors:4 dropped:0 overruns:0 frame:5

errors:4是为什么？

暂时的解决方法：现在我在单位的两台linux主机上暂时都运行一个ping 来确保网络时时畅通。

系统:
intel-P3 ，3c590x网卡,pc,内存128M,2硬盘,
uname -a:
Linux yhlwsrv 2.4.20 #2 二 11月 18 18:01:18 EST 2003 i686 unknown

所有module:
Module Size Used by
autofs 9248 0 (autoclean) (unused)

jbd 37328 9 (autoclean) [ext3]
usb-uhci 21664 0 (unused)
usbcore 57184 1 [usb-uhci]

其它装linux的机器也有类似情况

其中的19299为ping进程.
