Recently I found SSH and telnet behave strangely. After accepting
passwd, I could not get prompt. On little investigation, I found that
when I hangs, "ps -A" shows me:

<ps -A>
  PID TTY TIME CMD
<snip>
11159 ? 00:00:00 sshd
11161 ? 00:00:00 sshd
11162 pts/0 00:00:00 bash
11171 pts/0 00:00:00 hostname
11172 pts/0 00:00:00 hostname <defunct>
</ps>

On issuing "kill -9 11171", I get prompt. That mean "hostname" command
make SSH to hang. Server is having RH9. What could be the reason, and
what can be done to solve this issue?

Thanks in advance.
