Aged Processes

Dear all,

[color=red]Have you ever seen aged process like this before?

1150 ? 00:00 /DHS3bin/servers/sntpd
1151 ? 29730:39 /DHS3bin/x25/srv_suprout
23951 io2tty28 00:00 pre_login

i(1)ASSIPBXa> idle
idle 0.0%
idle 0.0%[/color]

I have encountered this before where when you telnet/login to the system, it was very slow. Soon after that we will have message "cannot fork". Then after that the CPU hang, and if you are lucky it will not crash (in my experience one of the incident cause CPU crash).

Any idea what can I do to fix this problem other that reboot the system every now and then?

thank you.

Try using this command to restart the process. It is case sensitive:

ASSIPBXa>dhs3_init -R SRV_SUPROUT

Good Luck

Can you remove the the PABX from the ip network wait 1min and after that check the idle, then if idle its ok, try to connect your pc directly to the ip interface of the cpu (without connecting to customer network) if you still have the cannot fork message try to kill inetd process and then execute "nohup inetd".
Let me have the feedback

Hi sadim,
As this site has a IP remote shelf, I can't remove the IP link.

Hi jpcx,
I'll try with the command dhs3_init -R SRV_SUPROUT .
Before that do I need to kill the process?
I'm not available on-site. Is it advisable if I would like to perform this remotely?

That command restarts the process, there's no need to kill the process first. As far as being on site or not, its always better but in this case I think it will either work or it won't, it should not cause a reboot.

May be problem with another process. Use "ps" command two times (with 30 sec interval) and check which process take all cpu time (used time will be increased in 30 sec).

Hi jpcx,

I have restarted the process and now it's working fine again.

I have another question: Is there a way to trace why this process is aging? Is there a way for us to prevent this?

thanks.

Is there any service interrupt during running dhs3_init _R SER_SUPPORT. In my experience, a process RLIS occupted allCPU resource. Only kill this process will fix the problem
