On <productname>Linux</productname>

<filename>/proc/sys/fs/file-max</filename> determines the

maximum number of open files that the kernel will support. It can

be changed by writing a different number into the file or by

adding an assignment in <filename>/etc/sysctl.conf</filename>.

On <productname>Linux</productname> the kernel parameter

<varname>fs.file-max</varname> determines the maximum number of open

files that the kernel will support. It can be changed with

<literal>sysctl -w fs.file-max=<replaceable>N</replaceable></literal>.

To make the setting persist across reboots, add an assignment

in <filename>/etc/sysctl.conf</filename>.

The maximum limit of files per process is fixed at the time the

kernel is compiled; see

<filename>/usr/src/linux/Documentation/proc.txt</filename> for
