    To Solve Errno 24: Too many open files. But I am not opening files Error “Files” include network sockets, which are a type of file on Unix-based systems. The maximum number of open files is configurable with ulimit -n

Solution 1

“Files” include network sockets, which are a type of file on Unix-based systems. The maximum number of open files is configurable with ulimit -n

# Check current limit
$ ulimit -n
256

# Raise limit to 2048
$ ulimit -n 2048

It is not surprising to run out of file handles and have to raise the limit. But if the limit is already high, you may be leaking file handles (not closing them quickly enough). In garbage-collected languages like Python, the finalizer does not always close files fast enough, which is why you should be careful to use with blocks or other systems to close the files as soon as you are done with them.

Solution 2

Setting ulimit -n will change the current limit for that terminal only. If you would like to change this limit so it exists across all terminal sessions (such as on EC2), you need to edit:

vim /etc/security/limits.conf

and add soft and hard limits for the number of open descriptors per user. As an example, you can paste this snippet in the file above:

*         hard    nofile      500000
*         soft    nofile      500000
root      hard    nofile      500000
root      soft    nofile      500000

This will set the limit to 500000 with every new terminal session. After editing, sign out and then back in, (or reboot if you are able and that’s preferable). Afterwards, you can run ulimit -n to confirm that it’s been set properly.
