I assume my problem comes from the memory. I have someting like 1.6GB +
0.5GB of swap but I'm experiency kernel bugs while unmapping swap
pages at unbound addresses. It is strange because it is not
swapping, or only slightly (less than 10MB) during some news.daily runs but the
crashes occur randomly.
FYI, This server accepts a full feed and feed it back several times
(around 250MB IN and 1TB OUT per day). The load is around 0.7 without SMP
and innd is idle more 70% of the time, innfeed 90% (2 instances).
I'm no longer using SMP because of some IO APIC problems forcing the
nmi watchdog to stop the kernel (for further investigations).

both are called highmem (CONFIG_HIGHMEM4G & CONFIG_HIGHMEM64G).
I'm running this :
# CONFIG_NOHIGHMEM is not set
# CONFIG_HIGHMEM64G is not set

AFAIK, my problems are well known but quite hard to fix. They are not
