We switched to rsyslog and since then seeing a huge increase in the log volume. Thanks for all the help!

Definately something to do with the > local syslogd under heavy load. Check that your syslog doesn't log synchronously. For the basic sysklogd, it means you need to have a "-" in front of your file names. And even with this, sysklogd's limits are quickly reached (between 300 and 1000 logs/s depending on the machine). For high loads, I strongly recommend syslog-ng. It's the only one I found which managed to log more than 10000 logs/s without dropping any : http://www.balabit.com/network-security/syslog-ng Regards, Willy
