[NTLUG:Discuss] Is there a such 'low power standby' phenomenons?

[m m]

Hi all:

Is there a such 'low power standby'  phenomenons?
what happpen to my box is that If I let the box idle for a while,
then nobody can conncet to my server, even ping the box,
the server is kind of 'dead'.
but if I physically go back to 'use' the box (any kind of use, edit a file,
telnet to some where...), the server become alive, all the servers
works fine.
I am think the NIC is bad, the something wrong on firewall rules,
or the kernel is not stable (just upgrated the kernel to 2.4.14).
If one of them cause the problem, then the problem should happen
any time, even that I am 'using' the box.

and idea?

Thanks.
