At 6:25 the cron started the regular locate data base update and other
tasks I guess it made the kernel reduce the size of the cache and fail.
I saw reports it happends with "non-tainted" kernels and with or without
nVidia driver, so perhaps thatīs a real bug in the mechanism used by the
kernel to kill a process that is eating all the memory introduced in 2.4.19.
I can fill a full bug report but perhaps any of you know about the
conclusion of this thread and Iīm just too stupid to find it.
Note that it doesnīt happend if the kernel doesnīt kill mozilla-bin for
days, when kernel kills this process is just a matter of hours before it
and from this point the cache size wonīt be reduced.
