> There is a race condition in these lines of code:
> openlog(sink->ident, LOG_CONS, sink->facility);
> syslog(sink->priority, "%s", ast_str_buffer(str));
> closelog();
> openlog interferes with all syslog calls in the process. Since asterisk
> is multithreaded, some other syslog message may be sent with syslog ident/facility, or some other call to openlog might interfere with this module's
> syslog call.
> This is not going to happen very often, but nevertheless it is an issue.
> I have resolved here piping to a different process which routes all messages
> to syslog with correct values,but implementation of a global syslog manager could be a more elegant solution.
