[parisc-linux] Squid-2.4.7 problem

[jsoe0708]

Hi all,

I try to install squid on a sarge install with a kernel 2.4.19-32. This squid
failled with data_page_fault.

As I would like to build an elementary FW there is no dev tools on this box.
So I try to debug the problem on my unstable (just update this morning) box
but here the problem is absolutly different: squid loop and a strace tells
me:
...
sched_yield()    =0
sched_yield()    =0
sched_yield()    =0
nanosleep({0, 2000001}, NULL)   =0
sched_yield()    =0
sched_yield()    =0
...

What should (could) I do ... 
in the first case I do not want to reinstall dev tools;
in the second one I do not know how to revert last apt-get update?

Thansk in advance,
    Joel

if this is reproducible, it is much better if you generate a core file
and look at that instead.

i suspect this is quite normal, depending on what squid is doing.

strace by default also only looks at the parent task. if any children
are fork()ed they will not be traced unless you tell it to.

Good idea I will try.

Hmm strace -f -p xxx 

says the same and no forks process?

I will try first the core dump.

Thanks,
