syslog-ng-2.0.6: after calling /etc/init.d/syslog-ng reload the process uses between 8 and 10% CPU. The effect does not occur when you use restart instead of reload. The effect did not occur in syslog-ng-1 Very annoying because reload is used by the logrotate script. Reproducible: Always Steps to Reproduce: 1. top 2. /etc/init.d/syslog-ng reload 3. see CPU load
This doesn't happen for me. Reopen with the output from emerge --info

Ok, found the problem. There were some program destinations configured: destination mail-alert { program("/usr/local/bin/syslog-mail"); }; destination mail-alert-perl { program("/usr/local/bin/syslog-mail-perl"); }; But these programs do not exist. strace shows that syslog-ng is looping while trying to start these processes. A reload makes the situation just worse (I think it just starts another loop). I have removed all non-existing program destinations from the config and now reload works fine. I will report upstream.
Same problem here, on two different arches (ppc and amd64). Perhaps this one could be reopened ?
