[syslog-ng]syslog-ng restart: postfix/nqmgr logline missing on next received e-mail

[Peter Bieringer]

Hi again,

during yesterdays problem my postfix statistics reporting tool
(pflogstats) reported about incomplete logging in 4 cases.

In all 4 cases I have syslog-ng restarted before.

Example:

Feb 12 22:22:54 syslog-ng[1871]: syslog-ng version 1.5.26 going down
Feb 12 22:22:54 syslog-ng[5317]: syslog-ng version 1.5.26 starting
Feb 12 22:22:54 syslog-ng: syslog-ng startup succeeded
Feb 12 22:23:01 crond: crond shutdown succeeded <- already learnt :-(
Feb 12 22:23:02 crond: crond startup succeeded


Missing nqmgr:

Feb 12 22:29:58  (7 minutes later, first received e-mail after
syslog-ng restart)

postfix/smtpd[5507]: C12F31386E: client=outgoing3...
postfix/cleanup[5521]: C12F31386E: message-id=<20030212180349....
postfix/smtpd[5507]: disconnect from outgoing3...
postfix/pipe[5525]: C12F31386E: to=<pbieringer@...

Normally (e.g. next delivered e-mail):

Feb 12 22:29:59 

postfix/cleanup[5521]: 3AEAD1386F:  message-id=<20030212180...
postfix/pipe[5525]: C12F31386E: to=<pbieringer@aer...
postfix/nqmgr[19977]: 3AEAD1386F: from=<bugtraq-r....  <--!!!!!
postfix/smtp[5530]: 3AEAD1386F: to=<pbieringer@aerasec.de>,...

Where is the nqmgr log line lost in first event?

Is this a well-known issue (feature or bug)? If yes, how can this be
fixed?

Pls. don't tell me that I have to restart every service after I
restart syslog-ng (already known: crond, now postfix, which one is
still missing?).
This would be a very unnice "feature". If bug is in a common used
glibc-version, then imho a workaround by syslog-ng would be required.
I don't like to loose loglines, you sure not, too.

Does this also happen if old syslogd would be used? Don't believe so.

It's all very strange...looks like I have to switch back to syslog,
loosing all the nice features :-(

        Peter, wondering
