Error starting ClamAV daemon

I can't get the ClamAV daemon to start on my Ubuntu 14.04 server. Here's what I get when I try to start the service:

sudo service clamav-daemon start
* Starting ClamAV daemon clamd  [fail]

When I try to run the clamdscan here's what I get

clamdscan test.jpg
ERROR: Could not lookup (null): Servname not supported for ai_socktype

When I run the normal clamscan on the file, everything is fine:

Here are the packages I have installed related to ClamAV:

The problem was memory usage. Apparently clamav-daemon uses about 300MB of memory when all the virus libraries loaded. I'm running on a small VPS with 1GB of RAM and mysql-server-5.6 takes up a big chunk of that. To improve performance I added performance_schema = off to /etc/mysql/my.cnf which reduced memory consumption by about 400MB! (why is this the new default in 5.6.6?!). Anyway, that freed up some memory which allowed clamav-daemon to start without a problem.

We've got it! :-) Type the following commands in a terminal Ctrl+Alt+T

sudo touch /var/run/clamav/clamd.ctl
sudo chown clamav:clamav /var/run/clamav/clamd.ctl

start clamd again!

I have run into this issue pretty consistently when provisioning vagrant boxes with clamav. Ensuring definitions have been downloaded and restarting the service consistently fixes it.

sudo freshclam && sudo service clamav-daemon restart
