[syslog-ng]Syslog-ng dies with logrotate

We am using logrotate to rotate our logs and when I send syslog-ng the HUP signal it dies. We am using version 1.4.11. Here is the config for logrotate. /var/log/serv/VPN.log { postrotate kill -HUP `cat /var/run/syslog-ng.pid` endscript } This is the same rule we use for all the logs. I thought the HUP signal problem was fixed? Should I try the newest 1.5.x version? Would this command work better? killall -HUP syslog-ng Thank you, sim
