hi.

i run a celeron450(clocked) with standard rh60 distribution.. no kernel
upgrades.

every night my slocate crashes.. have 1 dos partition with NT on it.
(and that's where the crash occurs.. as far as i thought, if the memory 64Mb
gets exhausted, cache is cleaned and smth bad happens)

i'll give all information that could lead somewhere...
