[ADMIN] Duplicating log lines from postmaster

I am seeing strange behavior with my postmaster logs, it seems to be writing out each line of a log entry 10 times. This seems to have started recently without any know config changes. I am running 7.3.2 on RedHat 7.3 i386. Below is a snippet from the logs. Thanks in advance for any help.
