Re: A few questions about lenny on Qube2

Hi chaps,

I'm still playing at this here.  So far I've set DMA off and upgraded to 
cobalt_2.6.30~rc8 kernel that Martin posted not too long back.

So currently it's running configure for the postgres source, and I think what's happening is that it's not crashing but going "lazy" - if thats the right term. Could this be something to do with CFS? Or could it be some other fault?  I guess I should try 2.6.22 at some point too should I?

I find it hard to describe what's going off, but here's what seems to be happening right now;

- I start 2 ssh sessions and in one start configure for postgres source, in the other I just started top.

- And for a while all seems fine; configure ticks away and top refreshes every second.

- Then top stops ticking over - but it'll refresh with a keypress. Anyway I exit top and try to run it again... nothing. I hit ctrl-c and try again... nothing.

- The configure script is still ticking over slowly.

- I try "ps ax" - it works; so I try it again... nothing.

- I try "ipcs" and "lsof" they both work.

- I try "ps ax" again... nothing. I hit ctrl-c and now it doesn't come back to the command prompt for a while.. say 5 minutes and eventually it's back.

- It's still going. Some commands still work, some just do nothing. proc/meminfo shows it's not eaten all the memory.

- If I try to start another ssh session I can log in, I get the motd, but I don't get to the shell - I guess I will eventually if I wait.

- I'm not sure what's going off with the configure script now, I can't do much or try and attach to it with strace.

It's just confusing.  Anyone have any ideas what I should look at?
