- The problem:
- 1 server(Auspex) with ~80 clients(all sun 4s).
- When all the clients try to boot(after a power outage) bootparamd
- on the server will consume ~70% of the cpu but few if any of the
- clients boot. Their boot requests are timing out.
- Apparently bootparamd can not service the packets fast enough so each
- of the following packets has already timeout by the time it is
- serviced.
-
- The temporary solution at this point is kill and restart bootparamd
- if cpu utilization is high with no clients booting.
-
- Can the client timeout be changed by adjusting a parameter
- within /tftpboot/boot.sun4c? Can anyone tell me how to do
- this? Or would it be better to change the queue size that
- bootparamd works with so that it can service the requests
- before they timeout?
-
- I realize that there other workarounds such as not
- booting on power up etc.. but I would prefer fixing
- the problem instead of working around it.

- Thanks
