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:
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
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!
