Bug#330105: libc6-dev: __FD_SETSIZE equals to 1024 is too small

["Damir R. Islamov" <dislamov@swsoft.com>]

Package: libc6-dev
Version: 2.3.5-6
Severity: normal
Tags: patch


In a web server with ore than 1000 Virtual Hosts in /var/log/apache2/error.log
could be seen multiple strings with

====================
Segmentation fault (11)

[warn] make_sock: problem listening on port 443, file descriptor (1068) larger 
than FD_SETSIZE (1024)
====================

The solution is editing __FD_SETSIZE value in /usr/include/bits/typesizes.h:
from
#define __FD_SETSIZE 1024
to
#define __FD_SETSIZE 32768
(value must be much greater than current one 1024) and rebuilding apache, 
sometime php,
openssl etc.

Please make default value of __FD_SETSIZE greater than now.
