Sorry Jamie it is actually a different error i think the last virtaulmin update i did a couple of days ago changed it still an error (see below) but it is deleting the user/group now which is better. sorry did not notice untill i went to manually delete the user.

Deleting home directory ..
.. done

.. Administration user failed! : Failed to query Postfix config command to get the current value of parameter home_mailbox: at ../ line 1360.

Here is the output of a top running average load on my physical machine.

Not Virtual anything, I am old school running my own hardware (dell power edge 1650) at a co-lo connected to fiber.  4G seemed like alot a couple of years back and ECC pricy too, but it is mostly being used however i seriously doubt it is causing this error!

So i stopped some processes and got top to look like this lots of free RAM tried deleting another virtual server and got THE SAME ERROR

However there is no postconf installed on this server i do not really want/need virtualmin to deal with email unless it can interface with Zimbra/Postfix?

root@mx1:/home/askidfj/public_html# postconf
The program 'postconf' is currently not installed.  You can install it by typing:
apt-get install postfix
-bash: postconf: command not found

Is your system perhaps low on RAM? I've seen this failure when the postconf command cannot be run due to lack of free memory ..

This is even more likely on an OpenVZ virtual system, as they often provide only "burstable" RAM that is not guaranteed to be available and causes this type of command failure.

Hello all

This error is ruining my day, when i try to delete a user, not using Webmin for email as i have another GUI specifically for email.  This never used to happen, expect it has to do with some Webmin update done at some time however not sure which version of Webmin it started happening with.

Also as the error states user and group do not get deleted

Thank you in advance
