Little note: mldonkey does NOT crash, your VM (kernel) kills the process
because of too high memory usage.

As I already wrote on this list and also made a comprehensive bug report
(Bug 1555 see here
http://savannah.nongnu.org/bugs/?func=detailbug&bug_id=1555&group_id=1409 )

the memory (and CPU and bandwith) eating behaviour on mldonkey ONLY appears
if you have a high-source file in your download list. A high-source file is
a file, where several houndreds of peers for that file are known.

You can - of course - also add more ram to your machine which mitigates the
problem (at least in respect to memory) somewhat. Also setting the
compaction_delay parameter down to 1 hr forces mldonkey to free that unused
memory it keeps locked sooner, thus also helping a bit.

However it IS a bug in mldonkey, no matter what people are saying who can't
reproduce it, and unless it is fixed, consider cancelling all files in your
mldonkey which are high-source and then restart mldonkey. At least it wont
drive your box into the constantly swapping mode.

Note CVS version 2.00+2 is *slightly* better but has the same problem. It is
less "greedy" thus it asks those sources less "fast" and eats less memory,
bandwith and cpu but it still suffers from the very same bug.
