after upgrade from 2.4.10pre8 to 2.4.10 I have weird problems, Xfree
sometimes shows up with 99.9% memory in top (on a box with 512 mb), and in
ps axl it has 4294989036 in the RSS column. When this happens the box starts
to kill some processes, starts heavily swapping (top reports > 400MB in the
cache, but the machine is heavily swapping!!!) and is completely unusable.
The problems is triggered when I start edonkey, some filesharing program
that creates checksums of large files (a couple of > 700Mb files).
Since this makes the machine completely unusable, and since it is not
happening on 2.4.10pre8 I guess it is a bug ;-)
This is a top snapshot:
46 processes: 43 sleeping, 3 running, 0 zombie, 0 stopped
CPU states: 3.8% user, 1.2% system, 94.6% nice, 0.4% idle
Mem: 514032K total, 511436K used, 2596K free, 1244K buffers
Swap: 358808K total, 10928K used, 347880K free, 466072K cached
