The problem is: A central syslog server logs huge number of maillog messages from a server. HUP signal is sent to the syslog-ng in postrotate instructions when logrotate runs. All log files are rotated properly except maillog. The old maillog messages are in the proper file, but no new file is created and thus nothing is logged for the facility . When I stop/start syslog-ng daemon it's working good. Yes, you are right. No start time of syslog-ng process gets changed when HUP is sent. Sorry my bad idea.

Hi,
I use syslog-ng-1.6.9-1. When the server should be killed by HUP signal (logrotate ) nothing happens (no time change in process table)
The HUP signal doesn't kill syslog-ng, it's effect is to reopen the destinations.
I attached list of HUP action and strace of the action.
You straced the kill command, not syslog-ng, so the output isn't useful.
The daemon uses pipes() and udp() as the sources.
Do you have any idea?
