Howdy,
I suspect you may be running out of RAM, and that the Linux kernel is killing various processes, including Webmin, in order to keep the system running.
What is the output of these two commands:
free -m
dmesg | tail -30
~# free -m

Howdy,
Unfortunately, it looks like you may not have enough RAM to run the services that you’re currently running.
I see messages about the Linux kernel killing processes to free up memory. In addition to Webmin being killed, it also looks like he killed ClamAV too.
You would either need to stop some services to free up RAM, or work with your provider to get more RAM in your server.
