Hi,

clears itself only after a reboot, when usage goes back to a sane 9-10%.
Is there an alternative solution ? I've never seen this happen before.

 	I may be talking through my hat here, but the /etc/host.conf
file lists hosts before bind, and since we do not run any sort
of name service here (tn.nic.in does it, I guess), all telnet(d) needs
to do is look at the complete /etc/hosts files on every box. Besides,
this also happens when telnet is passed the IP.

	Thanks.
