Package: syslog-ng
Version: 1.6.5-2.2
Severity: grave
Justification: renders package unusable
The syslog daemon randomly bug and log infinitely the same message in
/var/log/syslog about a call to accept() on a non socket.
This is a strace of the process when it bugs.
poll([{fd=2, events=POLLOUT, revents=POLLOUT}, {fd=8, events=0}, {fd=6,
events=0}, {fd=7, events=0}, {fd=4, events=POLLIN}, {fd=3,
events=POLLIN}, {fd=1, events=POLLIN, revents=POLLIN}], 7, 100
) = 2
write(2, "<43>Jun 13 10:59:36 smtp03 syslo"..., 97) = 97
accept(1, 0xbfffda90, [256]) = -1 ENOTSOCK (Socket operation
on non-socket)
getpid() = 573
time(NULL) = 1150189176
time(NULL) = 1150189176

With lsof, I can see that the file descriptor "1" is open on /dev/null.
I have in my configuration only one source without /dev/null:
source s_all {
internal();
unix-stream("/dev/log");
file("/proc/kmsg" log_prefix("kernel: "));
udp();
};
And there is no reference ton /dev/null in my configuration file so i
don't know why it tries to use it.
Moreover 16 servers have the same configuration file and 4 an other one
but the bug happens on the 20 machines newly installed.
