SCO 505 - disconnect from network

[andtony]

Hi everyone,

I'm not a Unix expert, but I had to maintain a few SCO 5.0.5 servers for months now. From time to time, some of them are disconnected from the network, usually the reboot is the only solution I have.

I figured out the causes of those disconnections were multiple :

- bad NIC ("well, duuuuuh ...")
- a device on the network which is throwing too much broadcast packets (Wifi hotspot or wireless NIC)

Now I have this server who's disconnected from the network the same way as the others did : no ping, but can work on the main screen.

When I type a sar command (sar 1 10), I have 99% on the %sys column. And when I try to figure out which process is taking so much CPU with this command :

ps -A -o "pid pcpu ruser args"

I'm having this result :

[...]
    4   0.00     root kmdaemon
    5   0.09     root htepi_daemon /
[b]    6  99.54     root strd[/b]
   43   0.00     root /etc/syslogd
   47   0.00     root /etc/ifor_pmd
   48   0.00     root /etc/ifor_pmd
[...]

It means the strd process is taking 99.54% of the CPU ? Does somebody know what can be the causes of this ?

Any kind of answer would actually be a big progress to me !

Thank you in advance

Anthony
