Hi all,

Does anyone know what the following message mean,
and how the message should be handled?

Any information will help.

Thanks,

I have the same problem on my HP9000. Some times it locks the system too.

Re: Telnetd Error in SYSLOG

This message is logged by the telnet daemon cleanup process when a kill -1 is sent to a telnetd child timeout. The connection went down and after telnetd waiting 30 seconds for a reply from a child process, it will issue the SIGHUP signal when that reply is not returned.

Look at the following kernel parameters and consider increasing them.
If you issue #kmtune for 11.0 or sysdef for 10.20, this will give you the current settings. Remember, 60 ntpty/nstrpty/nstrtel is the default number when installed. Check how many ptys are in /dev (#grep pty /stand/system)

nflocks
nfile
nstrpty
nstrtel
npty
nproc


Hope this helps.

Re: Telnetd Error in SYSLOG

Re: Telnetd Error in SYSLOG

Thank You for the faster response!
I will try this out as soon as the system (HP9000/K460, HP-UX 10.20) is available.
But, I already followed the HP document A5757455. It did not help.

When I increase the following kernels, are any of these parameters depend on other ones? Can I just increase npty, nstrpty to 4096 and nproc to 8192?
Here are my kernel current values:
# grep pty /stand/system
strpty_included
npty (MAXUSERS)
nstrpty 600

nflocks 6464
nfile 36010
nstrtel Doesn't exists
npty 800
nproc 6464

Thanks
Siva
