The last time this bug happened I checked with lsof and the number of shared 
and config files was ok (not so much, shared about 5, 40 downloading - like 
it was). But the real big rest was sockets. And Netstat showed only about 
130.

When it happens next time, I check it again.

I think downloading (40).

No, only edonkey - mldonkey is compiled only with edonkey support.

Good to know.
