[syslog-ng] HUP does not work

[Lumir Unzeitig (DHL CZ)]

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) 

I attached list of HUP action and strace of the action.

 

The daemon uses pipes() and udp() as the sources.

Do you have any idea?

 

Thanks for your help.

 

Regards
