A shot in the dark...

Have you searched /etc/crontab, root's crontab, PostgreSQL's crontab and
the crontabs of any automatic scripts that connect. I'm not sure about
Slackware but Red Hat and Centos run the cron.daily scripts at (wait for
it...) just after 4am.

Some of the default daily scripts like logrotate can have "side effects"
like restarting the service that writes to the log file being rotated.
