-This (read-only) file gives the number of files presently opened.

-It contains three numbers: the number of allocated file handles;
|
|
-the number of free file handles; and the maximum number of file handles.

-The kernel allocates file handles dynamically, but it
|
|
-doesn't free them again.
|
|
-If the number of allocated files is close to the

|
-maximum, you should consider increasing the maximum.
|
|
-When the number of free file handles is
|
|
-large, you've encountered a peak in your usage of file

+Historically,the kernel was able to allocate file handles
|
|
+dynamically, but not to free them again. The three values in
|
|
+file-nr denote the number of allocated file handles, the number
|
|
+of allocated but unused file handles, and the maximum number of
|
|
+file handles. Linux 2.6 always reports 0 as the number of free
|
|
+file handles -- this is not an error, it just means that the
|
|
+number of allocated file handles exactly matches the number of
|
|
+used file handles.
