Too many open files

mark_l · 05-28-2009, 09:34 AM

In my program, when I try to open a socket, I get the error: Too many open files.

I checked /proc/fs/file-max and this is 50727, and /proc/fs/file-nr is 2134.

What could be the problem?

Try reading about ulimit. It can limit the number of files that a given user can open at a given time, amongst many other things.

Thank you for the tip, but I increased nofiles in /etc/security/limits.conf from 1024 to 4096 and get still the same error.

If I check with ulimit -n, it gives 4096.

I found the problem.

It was a bug in my program. It was creating sockets all the time.

How can we find out which type of files are open?? so we can solve or close that socket/files??

The lsof command lists open files (as its name suggests

). It has many different options, so just read its manual page.

man lsof
