2.4.19 BUG in page_alloc.c:91

I can´t find a final conclusion about this topic.
What I found is that it happends some hours after the kernel killed a process that was eating the memory. Example:

Aug 26 13:07:22 ice kernel: Out of Memory: Killed process 18432 (mozilla-bin).
Aug 26 13:07:22 ice kernel: Out of Memory: Killed process 18443 (mozilla-bin).
Aug 26 13:07:22 ice kernel: Out of Memory: Killed process 18444 (mozilla-bin).
Aug 26 13:07:22 ice kernel: Out of Memory: Killed process 18445 (mozilla-bin).
Aug 26 13:07:22 ice kernel: Out of Memory: Killed process 18447 (mozilla-bin).
Aug 26 13:07:22 ice kernel: Out of Memory: Killed process 30410 (mozilla-bin).

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 that´s 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 I´m just too stupid to find it.
Note that it doesn´t happend if the kernel doesn´t 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 won´t be reduced.
