Duplicate logs in /var/log/messages
I am having an issue where all the logs for my server are written twice consecutively in /var/log/messages. Because the application running on this server requires a lot of disk I/O having duplicate entries written to disk is causing a lot of events to be dropped due to the unnecessary load. I have increased the queue depth and increased the priority_boost, which has reduce the number of dropped events from about 20k/hour to less than 700/hour, but stopping the duplicate entries would solve the problem altogether.
I have read about suppressing duplicate messages, but that solution appears to only apply to messages I define. Since ALL messages are written twice this would not work for me.
Any help would be appreciated.
