OK, after setting MAX_KMAPENT to 4000, the server only
lasts about 25 hours before a weird freeze -- which is
less than before. This weird freeze still answer to
ping, and consoles changes, but I can't log in, and
everything else stops to answer.
Can anyone give me a clue on how to pinpoint this
problem? I just need to know what is causing, so I can
think of a solution.
There is plenty free RAM, no swap use, and the server
load doesn't go any higher than 5.
I am really lost with lost problem.
Thanks...
