Can you (in openais.conf) disable logging to stderr and also logging to a file.
Make sure logging to syslog is turned on though.

I bet you wont have any further problems if you do this.

I looked again at the stack trace, and I see:

#1  0x0000003be088c74d in _L_lock_1685 () from /lib64/libc.so.6
#2  0x0000003be088c497 in __tz_convert () from /lib64/libc.so.6
#3  0x0000000000418a16 in _log_printf ()

Almost certainly this is caused by the following block:

	if (((logmode & LOG_MODE_FILE) || (logmode & LOG_MODE_STDERR)) &&
		(logmode & LOG_MODE_TIMESTAMP)) {
		gettimeofday (&tv, NULL);
		strftime (char_time, sizeof (char_time), "%b %e %k:%M:%S",
				  localtime (&tv.tv_sec));

I've no idea how either of those two standard system functions is able
to cause a deadlock, but its the most likely explanation.
Perhaps file a bug with the libc guys.
