Subject*** URGENT *** Memory deallocation probs with 2.0.27
Im still having this problem BIG TIME! This appears to be a kernel bug. 

I now have 96 megs ram in the computer. (triton II, P133, 2 eide 1
gig drives). I added the EXTRA ram in hopes that the prob would go away.
It had 64 and used to run nicely.

Here is a free:

total used free shared buffers cached
Mem: 95360 94024 1336 5104 144 2580
-/+ buffers: 91300 4060
Swap: 32252 16464 15788

Here is what is running: (ps -aux)

As you can see, only the mud is taking up a significant amount of ram
(almost 20%), but this was NEVER much of a problem before. The mud does
NOT run as root and worked fine on a 1.3 and a 2.0.0 kernel. I have the
slackware 3.1.0 distribution which has the LATEST libs and kernel 2.0.27.
I have the same problem with 2.0.21 so SOMETHING happened between 2.0.0
and 2.0.21

Why are my USED buffers so high!?!?!

This has got to be a kernel problem. I run the exact same stuff on an
alternate server running 2.0.0 and it runs happily.

Also I can write a program (eatmem) that allocates 2 megs ram then crashes
and running this enough times will crash the server. This is runing NOT as
root also.
