I got this issue first time on 2.6.16 (hardened packages released with
some delay).

Hmm. Can you reboot that system with 160 days update, just to be sure it
is have sense this compare it to other systems?

Hardened insists on very stable CFLAGS.
My servers/workstation:
    CFLAGS="-march=pentium-m -O2 -pipe"
    CFLAGS="-O2 -march=pentium4 -pipe"
    CFLAGS="-march=k8 -O2 -pipe -fforce-addr"
Server without zombie issue:
    CFLAGS="-march=pentium4 -O2 -pipe -ftracer -fprefetch-loop-arrays"

Time overflow? In 2-10 days? Don't think so.

Important question: do you recompile overall system after upgrading any of
toolchain packages (linux-headers/glibc/gcc/binutils)? I see you're using
newer gcc (4.x.x), but do you recompiled everything with it?

P.S. I think it's time to try sysvinit for me.
