Hello all, I have been getting several strange effects after adding some 
memory to my system.  (total of 48mb now.)

First thing I noticed is that vi (and it's derivitives nvi, etc.) and talk
would core dump upon invocation.  reboot fixed.

Second thing, find command always produced a bus error.  Reboot fixed.

Third thing, a 'du' locked up my system and necessitated manual fsck'ing 
upon reboot.

Fourth thing, X sometimes exits prematurely with a buserror or segfault.
Not usually on its own, though, when I've done something (new window or
something) to upset it. After this happens, X exits almost immediately
with the same error when restarted (until reboot, of course.)

Fifth thing, have rebooted my machine left the room to get a coke and
returned to find it rebooting again...  weird, huh?

I bought 2 4x32mb simms (rated at 60ns although I use them at 70) and 
added them to the four 4MB sims that I already had.  Is this the
possible effects of defective RAM? or should I recompile the kernel with
the option of more than 32 MB of memory or something like that.  

Thanks, 

Sean Emery
