My server is stopped work unexpectedly

[Mousa55]

We have rp8420 server with 4 partition, at the last Wednesday the first partition and the four partition are stopped work in an unexpectedly, I don’t know what is the main reason. Where I can’t pinging into two server from the my PC and from the server when using the cross cable, I don’t found any response (don’t pinging). But I can login to server from the console (CO) from the MP and the server it is working fine and all application and database it is fine.
and The problem had stopped the server back today on one server with the same problem.
Where I can’t pinging to my server from my pc and from the same server with using a cross cable
And the status of the network card it is UP and running.
I am solved this by reboot the server, and this Not the ideal solution

Note: I am using the top command and I am found the hpnpf process
This process has been consuming 100 % from all 8 CPU and I tried to kill the process
But it back again.

how to solve this problem and kill the hpnpf process.

Shalom,

Mine to.

What you do now is do some post mortem analysis.

Connect to the console and look at the GSP logs.

Take a look at /var/adm/syslog and see if the logs there provide any clue to the problem.

This process is apparently associated with the print spooler.

It seems associated with older versions of the OS, but of that I'm not certain.

Hi Nejad:

Sounds like you've got a runaway process with possibly an open file, for example.

Use glance to investigate and drill down for information on the process pid.

launch glance
Type "?" for a list of commands
open files by PID
wait states by PID
etc.

>the hpnpf process. This process has been consuming 100 % from all 8 CPU and I tried to kill the process but it back again.

If killing it just creates another, you may just try "renice -n 20", that way another isn't created and perhaps you can get some work done.

You might want to use "UNIX95=1 ps -Hfe" to see what the process tree that has hpnpf looks like. If init is respawning it, not much you can do except edit inittab(4).
