2.23. I just upgraded my Linux system to glibc and now I get
errors whenever I try to link any program.
2.24. When I use nscd the machine freezes.
+2.25. I need lots of open files. What do I have to do?
3. Source and binary incompatibilities, and what to do about them
Note that I have at this point no information about any other platform.

+
+{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.
