Take a look at how you are running snort

Wrong Way examples

/usr/sbin/snort -b -d -D -i eth0 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort
/usr/sbin/snort -A -d -D -i eth0 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort

Right Way

 /usr/sbin/snort -d -D -i eth0 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort

What’s causing this problem?

You have enabled one or more of these switches when running snort: -A -b

More details please….

Those switches translate to ALERTMODE and BINARY_LOG

#### Logging & Alerting

# NOTE: NO_PACKET_LOG and BINARY_LOG, ALERTMODE, etc. are mutually
# exclusive. Use either NO_PACKET_LOG or any/all of the other logging
# options. But the more logging options use you, the slower Snort will run.
