What is reloading postfix twice at 4AM

[getgray]

I get a daily reload of Postfix. It's happening twice, back to back.

Jan 8 04:02:08 tn2 postfix/postfix-script[8927]: stopping the Postfix mail system
Jan 8 04:02:08 tn2 postfix/master[10112]: terminating on signal 15
Jan 8 04:02:08 tn2 postfix/postfix-script[9011]: starting the Postfix mail system
Jan 8 04:02:08 tn2 postfix/master[9013]: daemon started -- version 3.2.2, configuration /etc/postfix
Jan 8 04:02:08 tn2 postfix/postfix-script[9030]: stopping the Postfix mail system
Jan 8 04:02:08 tn2 postfix/master[9013]: terminating on signal 15
Jan 8 04:02:09 tn2 postfix/postfix-script[9112]: starting the Postfix mail system
Jan 8 04:02:09 tn2 postfix/master[9114]: daemon started -- version 3.2.2, configuration /etc/postfix

I've looked in the cron files, I don't see anything causing it there.

I' d be grateful for some assistance finding where this is configured and what is triggering it. Pointers on where to look, etc.

I would guess it's logrotate and you have two file rotations that tell it to bounce postfix after each file.

Thank you, I'll try to dig through those as see if one (two) of them is doing it.
