BASE not getting Updated

[mandraid]

I am running Snort 2.9.11.1 on Ubuntu server. I have also installed BASE and barnyard2. When I run snort, I see snort.u2.nnnnn files being generated (not empty). I run barnyard2 as such:
sudo barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -f snort.u2 -w /var/log/snort/barnyard2.bookmark -g snort -u snort -v
Output:
Running in Continuous mode

Barnyard2 spooler: Event cache size set to [2048]
Log directory = /var/log/barnyard2

Yet I do not see new events being generated in the BASE interface.
