sysklogd ships with inefficient default settings for Postfix

From Bugzilla Helper: User-Agent: Mozilla/4.79 [en] (X11; U; Linux 2.4.18-12.5 i686; Nav) Description of problem: # tail -11 /etc/postfix/README_FILES/LINUX_README LINUX SYSLOGD PERFORMANCE ========================= LINUX syslogd uses synchronous writes by default. Because of this, syslogd can actually use more system resources than Postfix. To avoid such madness, disable synchronous mail logfile writes by editing /etc/syslog.conf and by prepending a - to the logfile name: mail.* -/var/log/mail.log Send a "kill -HUP" to the syslogd to make the change effective. # cat /etc/syslog.conf | grep maillog mail.* /var/log/maillog # rpm -qf /etc/syslog.conf sysklogd-1.4.1-8 # rpm -q postfix postfix-1.1.7-2 Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Read interesting files randomly. ;-) Additional info:
This is performance issue, I guess.
Is this still a issue? It can't be so hard to fix this that it takes 2 years to fix. It's only matter of adding one minus sign to /etc/syslog.conf file. My /etc/syslog.conf has these lines: # Log all the mail messages in one place. mail.* -/var/log/maillog and it have been working well for years.
For starters, this should be filed against syslog, not postfix....
agreed, this is not a postfix issue but rather a sysklogd issue, reassigneing to notting
Seems a sensible fix
Fixed in 1.4.1rh-21.
