Hi
        I have problems with the swap code in 2.2.15pre9 (newer pre's
        are worst). I have obtained the following errors:

swap_duplicate: entry 0816e000, offset exceeds max
VM: killing process hsc
swap_free: offset exceeds max
swap_free: offset exceeds max
swap_free: offset exceeds max
swap_free: offset exceeds max
swap_free: offset exceeds max
swap_free: offset exceeds max
swap_free: offset exceeds max
swap_free: offset exceeds max

And the swap is not full, it is almost empty when I receive this
message:

vexeta:/usr/src# free
             total used free shared buffers cached
Mem: 258060 254868 3192 32724 93084 86448
-/+ buffers/cache: 75336 182724
Swap: 248996 7148 241848

The problem happens when I am mapping a file in one process (around
400MB) with a lot of small mmaps. It kills other processes, not the
one which is using all the memory. I can give you more information on
request (Basically is an implementation of virtual memory in user-space).

Configuration:
Athlon 500Mhz
IDE
256MB RAM

more information on request. If you need to test something or I can do
something to help let me know.

TIA, Juan.
