I am running into a problem all of a sudden; all my applications and the server was running fine and all of a sudden I see the number of open files shoot up.

I am checking it with this command:

cat /proc/sys/fs/file-nr

When I check with this it shows 44544 0 128000, so 44544 is the number of open files.

But when I check with this command - lsof | wc -l it shows - 28384.

So which one is correct?

My max open files limit is 65535

ulimit -a
open files                      (-n) 65535

I want to know the top 5 processes that are using more open files. I can get this from lsof but the count shown here is very different from the other command I mentioned above.

Can I get the details of the processes counted by this command cat /proc/sys/fs/file-nr?

According to the below mentioned link it says we cannot, How to display open file descriptors but not using lsof command

Is there a work around for me? I need to find which process started using more open files all of a sudden.

UPDATE Sorry guys for the trouble . I found the mistake which i was doing i was NOT checking lsof|wc -l from root. that is the reason i was seeing a huge difference.

still there is a difference between the output of file -nr and lsof | wc -l (from root). lsof count is more than file -nr count. the reason for this is , file -nr ignores some of the directories (which are considered as files by lsof) i found this reason by a litle research on google itself. anyways! thanks guys for all the help!
