Question: Webmin keeps crashing on my VPS. Why does this happen and how can I fix it?
From our experience, webmin seems to become non-responsive when running on “low memory” VPS’s (typically those with 256 megs of ram or less).
If you attempt to connect to webmin (port 10000 by default) and get an unable to connect message, do the following:
1. ssh in to your server
2. as root, type :
/sbin/service webmin restart
Note, that “service” will restart webmin on a RedHat/Centos based VPS. If you are running a different Linux flavor you’ll need to use the service management for that distribution.
You should also make sure webmin is set to start automatically on reboots by running:
/sbin/chkconfig webmin on
I tried to connected to webmin on my VPS today and got the error :
Firefox can’t establish a connection to the server at 100.100.100.100:10000.
(where 100.100.100.100 is the IP of your VPS)
What is wrong?
This means webmin has crashed and is a warning sign that you are likely using more memory than your VPS has installed. On VPS’s with low memory, webmin seems to be one of the first things to lock up.
You can restart it by ssh’ing to the server and typing:
/sbin/service restart webmin
You could also reboot the entire VPS in your control panel as last resort if you do not have ssh access from your current location.
