That is clear that this is the number of the maximum limit for all processes. 
But I think the 1024 limit, it is a limit for one process.

My mldonkey has its own user. And as I watched (lsof), this user can have more 
than 1024 connections/files open. But mldonkey not, because mldonkey print 
error messages at this situation, like, too many open files, or something 
like that.

So I think 1024 it is not an user limit.

An it is true that only the mldonkey process is affected, but this sucks 
enough. Because I can't connect with telnet anymore, I can't add new download 
links and so on.

At the moment I have only "353" open connections from this process, so perhaps 
mldonkey opens so much connections by accident. So this is the reason, why I 
am writing. If it is a Bug or just normal. If it is normal you can increase 
this limit of course.
