Stuck at refreshing and rechecking configuration.

Installation went well, it seems. Two things:

Re-checking and refreshing configuration in yellow bar doesn’t go away. Process gets stuck at “SpamAssassin and Procmail are installed and configured for use.”, sometimes the “ClavAV is installed…” and webmin service stops immediately afterwards. Which I have to manually restart.
A manual “virtualmin check-config” returns:
“Failed to query Postfix config command to get the current value of parameter recipientbccmaps:”

and sometimes:

“Use of uninitialized value $out in pattern match (m//) at /usr/share/webmin/webalizer/webalizer-lib.pl line 270.
Use of uninitialized value $ver in substitution (s///) at /usr/share/webmin/webalizer/install_check.pl line 17.
ERROR: Webalizer does not appear to be installed on your system, or has not yet been set up properly in Webmin’s Webalizer Logfile Analysis module. If your system does not use Webalizer, it should be disabled in Virtualmin’s module configuration page.”

Any help? Couldn’t find anything worthwhile anywhere.

None of this should happen on a fresh grade-a supported system.

What distro are you using? Did you use the installer script on a fresh OS? Are you using an OpenVZ VPS?

Using an Ubuntu 14.04 x64 distro on a Digitalocean VPS. Followed this guide to install on a fresh OS: https://www.digitalocean.com/community/tutorials/how-to-install-and-utilize-virtualmin-on-a-vps

Okay, the guide looks pretty good and should work properly. How much memory does your VPS have? What output do you get for this command: cat /proc/user_beancounters

The problems you’re encountering look like you’re running out of resources.

512 MB, low-end VPS to get hands dirty. Command returns “No such file or directory”.

Maybe because DO runs KVM and that’s not supported?

It seems that the service also stops on other tasks as well. Mainly on re-checking and refreshing configuration though.

Yeah that’s right, the beancounters file is an OpenVZ thing. You might be running out of memory, 512 MB is a bit few to run all services. What’s the output of “free”? Also check /var/log/syslog for out-of-memory kill messages.
