Description Petri T. Koistinen 2002-09-02 15:56:01 EDT

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. ;-)

Comment 1 Petri T. Koistinen 2003-05-17 12:07:37 EDT

This is performance issue, I guess.

Comment 2 Petri T. Koistinen 2004-03-01 12:13:55 EST

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.

Comment 3 Chris Ricker 2004-03-26 08:57:46 EST

For starters, this should be filed against syslog, not postfix....

Comment 4 John Dennis 2004-03-31 17:34:25 EST

agreed, this is not a postfix issue but rather a sysklogd issue,
reassigneing to notting

Comment 5 Alan Cox 2004-06-18 13:59:30 EDT

Seems a sensible fix

Comment 6 Bill Nottingham 2004-06-28 15:51:46 EDT

Fixed in 1.4.1rh-21.
