    Default AWS EC2 instance out of memory???

    I'm having some stream quality issues, so I logged in to the Wowza Streaming Manager and noticed the "Total Memory" bar on the usage plot is at almost 100% and the "Total Disk" bar is at 100%. I went to the live Application and tried to restart it and get an error box saying:
    "Communication Error 1001
    Could not connect to Wowza Streaming Engine Manager. Make sure Wowza Streaming Engine Manager is running and accessible.
    The target server failed to respond"

    So I logged directly into the EC2 instance via ssh and see this:
    15 package(s) needed for security, out of 38 available
    Run "sudo yum update" to apply all updates.
    Amazon Linux version 2016.03 is available.
    grep: write error"
    The I try "sudo yum update" and get
    "[ec2-user@ip-172-31-46-250 ~]$ sudo yum update
    Loaded plugins: priorities, update-motd, upgrade-helper
    Could not create lock at /var/run/ [Errno 28] No space left on device

    Can't create lock file; exiting"
    So I look at /var and see:
    [ec2-user@ip-172-31-46-250 ~]$ df /var
    Filesystem 1K-blocks Used Available Use% Mounted on
    /dev/xvda1 8123812 8107424 0 100% /

    So it looks to me like my streaming engine manager is having some functioning problems due to this disk being totally full? I have no streams running right now, and have no idea what to do to fix this. Is there some way to reboot the whole instance that will install the updates and clear out this memory problem and hopefully get the streaming engine working again properly?
    Please please please someone tell me what to do to fix this!

    So I had 6 GB of wowza logs sitting around. I deleted them and let's see if things work any better...
