Hi all

Cannot understand, does it a bug or just a misconfiguration. In my Dovecot there are 3 files of logging (debug, info and .log) While executing logrotation, the new files are created, but old ones, namely dovecot.*.1 are still in use by the process

I use next logrotate config for dovecot: /var/log/dovecot.log /var/log/dovecot.info /var/log/dovecot.debug { daily rotate 14 missingok notifempty compress delaycompress sharedscripts postrotate doveadm log reopen chmod 666 /var/log/dovecot.log chmod 666 /var/log/dovecot.info chmod 666 /var/log/dovecot.debug endscript }

Here is the logger process in memory: root 19140 0.0 0.0 4140 1576 ? S Mar12 0:06 dovecot/log

Here the files it uses after the daily logrotation: # lsof -p19140 |grep log ... log     19140 root   33w   REG        9,3      811  417675 /var/log/dovecot.log.1 log     19140 root   34w   REG        9,3  2842123  417681 /var/log/dovecot.info.1 log     19140 root   35w   REG        9,3 14853918  417683 /var/log/dovecot.debug.1 ...

On manually issuing 'doveadm log reopen`  used files are changed to # lsof -p19140 |grep dovecot\\\. ... log     19140 root   33w   REG        9,3       0  417651 /var/log/dovecot.log log     19140 root   34w   REG        9,3  121374  417690 /var/log/dovecot.info log     19140 root   35w   REG        9,3  916153  417691 /var/log/dovecot.debug

as it is expected to be What can be the root of the issue?

I use Dovecot as LDA for Postfix with system users, mbox mail format. System Slackware 12.0 x86, Postfix 2.4.5, Dovecot 2.2.36. Interconnect Postfix-Dovecot was made via mailbox_command Dovecot compiled from sources

Logging configuration (file conf.d/10-logging.conf) contains the following:

log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.info debug_log_path = /var/log/dovecot.debug

auth_verbose = yes auth_verbose_passwords = yes auth_debug = yes mail_debug = yes verbose_ssl = yes

plugin { }

Could the fact, that Postfix require Dovecot logs to be accessible someway, result in such a weird behavior? To allow other processes to access Dovecot logs I had to chmod 0666 all the current logs while integrating Dovecot into Postfix delivery (please see `chmod' commands in the logrotate config above)

Thank you Denis Razoumovskiy
