2.25. I need lots of open files. What do I have to do?
{AJ} This is at first a kernel issue. The kernel defines limits with
OPEN_MAX the number of simultaneous open files and with FD_SETSIZE the
number of used file descriptors. You need to change these values in your
kernel and recompile the kernel so that the kernel allows to use more open
files. You don't necessarily need to recompile the GNU C library since the
only place where OPEN_MAX and FD_SETSIZE is really needed in the library
itself is the size of fd_set which is used by select.
The GNU C library is now (nearly) select free. This means it internally has
no limits imposed by the `fd_set' type. Instead almost all places where the
functionality is needed the `poll' function is used.
If you increase the number of file descriptors in the kernel you don't need
to recompile the C library. The remaining select calls are in the RPC code.
If your RPC daemons don't need more than FD_SETSIZE file descriptors, you
don't need to change anything at all.
{UD} You can always get the maximum number of file descriptors a process is
allowed to have open at any time using
number = sysconf (_SC_OPEN_MAX);
This will work even if the kernel limits change.
