Switch to ULOG instead of LOG as LOG relies on Syslog which was *NOT* meant for high volume traffic. The other solution that I have proposed in the past is to set up TCPDump or Snort and have it sniff the headers out of packets and dump them to a log file and then post process said log file to extract what you are wanting and store it accordingly.
