order in the syslog output. i.e. several messages that had been time-tagged
at 18:07 showed up after 18:17 in the log file. This may be another
indication that there is an undesirable interaction with syslog.
FYI, by default syslog does synchronous writes to the file specified in
syslog. So depending on how busy syslog is and how busy the disk(s) that
contain that syslog file then you could run into some poor performance. You
could prepend the log file in /etc/syslog.conf with "-" (like
"mail.* -/var/log/mail.log") and see if performance improves.
