/proc problem

/proc problem

[Burján Gábor]

Hi,

I've a mysterious problem with Linux kernels on a production system.
The box is a web frontend machine and the problem is that after a
couple of days of running one of httpd process "sticks" in.  Commands
w, ps and their friends usually hang after this case.  I cannot stat
the files under /proc/<PID-of-this-httpd-process>/, so I think this
should be a kernel-related problem.  Only the reboot helps.

I tried out a lot of kernel versions: 2.4.10, 2.4.19, 2.4.19rmap14b
(the last one with the new procfs code), but these didn't help.

Any idea?

/proc problem

[Toni Van Remortel]

Hi all,

I just added some /proc support to my module to run on an EP405, but
when I load my module, I get
unresolved symbol __extendsfdf2
Google didn't get me any further.
Code can be found at http://linemb.d-sciencelab.com/rt_mod.c

Thanks,

You're trying to do floating-point math. The kernel doesn't do
floating-point.

Hmm. Is there a work-around? Because the control interface (written with
FLTK) does use floating points and works.

Silly me. The FLTK app is statically compiled.
Just found a kernel miss-config indeed.

tnx for the reaction.
