Hi,
I'm running Virtualmin 4.08.gpl on an Ubuntu 14.04 LTS t2.micro AWS instance.
I have all the "regular Virtualmin servers" running but the ClamAV server always crashes after some hours and I need to reboot the system.
The t2.micro instance have 1GB RAM but the result of /var/log/clamav/clamav.log when i try to restart the ClamAV service (/etc/init.d/clamav-daemon restart) is:
Sat Jul 12 18:40:10 2014 -> +++ Started at Sat Jul 12 18:40:10 2014

Any ideas?
Looks like you don't have enough memory, what is the output of "free -m"?
With ClamAV running again (after a reboot):
total used free shared buffers cachedMem: 992 908 84 6 15 205
-/+ buffers/cache: 687 305
Swap: 0 0 0
Yeah, memory is quite full and you don't have swap space. You might need to upgrade your memory or ask your hoster to make swap available.
This creates a fake swap file on CentOS 6, this should help. EC2 does not have swap available. I use this on some virtual systems that run database software that requires swap.
dd if=/dev/zero of=/swapfile bs=1M count=512mkswap /swapfile
swapon /swapfile
free -m should now show the 512MB swap
add this to /etc/fstab to enable swap at boot time
/swapfile swap swap defaults 0 0If you don't then you need to run "swapon /swapfile" after every reboot
