Hi all, I have installed syslog-ng via apt-get on an Ubuntu 8.10 server. I have added the below to the configuration file: template t_smtp { template_escape(no); template("NOOP HELO localhost MAIL From: admin@example.com RCPT To: scott@example.com DATA From: admin@example.com To: scott@example.com Subject: Syslog msg from $HOST - [$FACILITY:$PRIORITY] $PROGRAM $S_DATE [$FACILITY:$PRIORITY] $MSG . QUIT "); }; log { source(s_all); filter(f_at_least_notice); destination(d_logfile); }; destination d_logfile { program("sendmail -bs > /var/log/syslog-email.log 2>&1" template(t_smtp)); }; For some reason with the above config after a message hits d_logfile the CPU usage jumps to 100% and stays there until syslog-ng is stopped. It's like some file it uses during the process gets locked and the thing jams up waiting forever. The only way to solve the problem is remove the program() entry and replace it with file("/var/log/temp.log" template(t_smtp)); in which case it works fine. To test the program()destination I created a php script that just slept for 10 seconds <?php sleep(10); ?> And called it in d_logfile { } with program("/usr/bin/php /tmp/sleep-test.php") And sure enough the cpu jumped to 100% and stayed there until syslog-ng was stopped. Can anyone see a program with my above config or suggest why syslog-ng can't cope when the program() doesn't return immediately?
