The value in file-max denotes the maximum number of file-
handles that the Linux kernel will allocate. When you get lots
of error messages about running out of file handles, you might
want to increase this limit.

-Historically, the three values in file-nr denoted the number of

Attempts to allocate more file descriptors than file-max are
reported with printk, look for "VFS: file-max limit <number>
