After upgrading to glibc-2.3.2 (from 2.3.1-17) a cgi program of mine
suddenly started to hang.
The program is using syslog() to report error conditions.
After a bit of investigation I came to the following test case:
#!/usr/bin/python
import syslog
import sys
print """\
content-type: text/plain
""" ; sys.stdout.flush()
syslog.syslog ("Should be ok")
print "First syslog run" ; sys.stdout.flush()
syslog.openlog (
"test_libc6", syslog.LOG_PID, syslog.LOG_LOCAL1)
print "openlog run" ; sys.stdout.flush()
syslog.syslog ("Should be also ok")
print "finished" ; sys.stdout.flush()
When calling this program, the web browser seems to hang, the apache
process used for the processing of this request hangs:
F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME
CMD
5 S 33 11536 11534 0 69 0 - 1891 rt_sig ? 00:00:00

When using gdb to debug the hanging process, I get the following
backtrace:

Detaching from program: /usr/sbin/apache, process 11536
When I don't use mod_python as an app accelerator the problem does not
occur.
When I take out the openlog() line the problem does not occur.
The version of apache I'm using is:
ii apache 1.3.27.0-2 Versatile, high-performance HTTP server
The version of mod_python is:
ii libapache-mod- 2.7.8-7 An Apache module that embeds Python 2.2
with
The python version I'm using is:
ii python2.2 2.2.3-2 An interactive high-level object-oriented
