how to clear the caches of snort/barnyard?

["闫振宇" <yanzhenyu () 55tuan com>]

Hi,all
      I rewrited  my snort.conf.I wanted  snort to output snort.log.and I started up snort&barnyard,but it seemed that 
the new configuration file  didn't work. The 'spool filebase'   option of barnyard  was  merged.log not snort.log.

1st.  snort.conf

........

# unified2
# Recommended for most installs
  output unified2: filename snort.log, limit 128
# output unified2: filename merged.log, limit 128, nostamp, mpls_event_types, vlan_event_types
# Additional configuration for specific types of installs
# output alert_unified2: filename snort.alert, limit 128, nostamp
# output log_unified2: filename snort.log, limit 128, nostamp 


2nd.Start up snort&&barnyard
snort -c /etc/snort/snort.conf -i eth0 
/usr/local/bin/barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -f snort.log -w /var/log/snort/barnyard.waldo
