Unable to save resume file. Too many open files

Question

Every time i am getting Unable to save resume file. Too many open files error in transmission application. I got solution in this post.

sudo sh -c "echo fs.file-max=$(dc -e '2 20 ^ p') > /etc/sysctl.d/file-descriptors-max.conf"
sudo service procps restart

But sudo service procps restart output:

stop: Unknown instance: 
procps stop/waiting

Can anyone please help me out? I am using Ubuntu 12.04 LTS.

Answer 1

My current Ubuntu 12.04 installation shows 98930 as value for file-max

> cat /proc/sys/fs/file-max
98930

If you want to raise this value, you have several options.

1. Create a new file: echo "fs.file-max=$(dc -e '2 20 ^ p')" | sudo tee /etc/sysctl.d/60-file-descriptors-max.conf. This command writes the echoed line into the file. If the file exists it is silently overwritten. According to the documentation you should choose the value 60-*.conf for user values. After you have done this you should enter sudo service procps start and not restart like in your example. As you can see with the command sudo service procps status the program is not running.
2. Directly write into the file in the proc filesystem: echo $(dc -e '2 20 ^ p') | sudo tee /proc/sys/fs/file-max. After the command the value is set and will be used. You can use the above mentioned cat command to get the current value.
