How To increase the limit for file handles

There are cases when you get a lot of error messages about "running out of  file handles", increasing this limit of this handler can solve this issue. To change the value, just write the new number into the file as below:

# cat /proc/sys/fs/file-max
8192

# echo 943718 > /proc/sys/fs/file-max

# cat /proc/sys/fs/file-max
943718

This value also can be changed using "sysctl" command. To make the change permanent, add the entries to /etc/sysctl.conf

# vi /etc/sysctl.conf
fs.file-max = 943718
