On my NAS (an incredibly basic and reliable DNS-323), I use mldonkey to download files.
It worked quite well during the last 3 years, but it seems now mldonkey doesn't work.
Indeed, each time I start mldonkey, it crashes after a few hours of execution, complaining for
Too many open files. Due to the fact mldonkey worked without any trouble during years, I wonder what can make it fail.
According to some web results, I tried to
ulimit -n 5000, but it didn't changed anything : mldonkey continued to fail.
What's more, it seems that when I restart mldonkey (but not the NAS), it fails far faster (which lead me to think open files are not mldonkey ones.
How can I check which files are open, and what could I do to fix that?
