HP UX Console hanging

[Elias Abboud]

Hi everyone,

I am facing a problem. When I boot my hp ux system it works properly. no error messages. After a while the console hangs and stops responding. when this happens, also Telnet from my laptop does not give the login prompt just a blank screen. ftp replies with the login prompt but when I enter username and password it hangs also. ping to the server replies normally.

Any help is greatly appreciated

Thanks in advance

Hi!
Does this accour everytime after You reboot (is it repeatable every time) ?

Do You have a mirror copy of VG00? If so, try to boot from the other VG00 disk.

Hi

Looks like there you are running out of pty's, there might be some process which is spawing, try and boot in single user mode to make sure if everything is ok if it is then there might be some process in multi user which is creating this issue.

Could you please send details re the server model ?
Is this R380 or D270 ?
These models have such a behavior until you replace old system disk.
Do you see any error messages in /var/ad/syslog/Oldsyslog.log after reboot ?

Hi everyone,

I have no mirroring. This happens after a while from booting. no special activity on the system, it just hangs by itself. I will try booting in single user mode to see if this also happens. If it is a respawning process, how could i detect it???

no errors in /var/adm/syslog/Oldsyslog.log

It is a D class HP9000 server. HPUX 10.20

Any help will be greatly appreciated.
Thanks in advance

hi,

do you have any of your filesystems full.turnoff any extra device (such as external cd drive ,dat drive ,optical drive ,etc) and boot server again.also disable the cron processes and check the system.

Elias,

What Firmware version is installed on the server ?
I had such a problem on some computers. On part of them the problem was resolved by firmware upgrade and on the rest by system disk replacing.
The firmware upgrade is prefeerable.

Hi Elias,
Ive seen maybe most current cases from console not willing to work (thas was the most messy task - I spent weeks on it...), to connections failing because no more available tty..
In your case I would start by keeping for myself 2 open sessions at minimum (do you have an X emulation?) or keep the console connected AND some other connections.
Now to make it short has anything been installed lately? Has /etc/inittab been modified (check timestamp!).
If No:
then you have chances to have a massive load on the box that lets onling ping saying the box is alive... Use on one session top running and watch.
Or you have some problem with your inet services (any daemon dying?)
Is there some oracle running?
It can be the listener cannibalising...
It can be you IP stack...
It can be you network driver (do you have another lan you can use?)...
...

Good luck
Victor
