Two very small Bugs

Hello All, I have two bugs and I will like to fix it by myself or knowing if someone hit the same bug and if I am not the only one.

The first bug is the stupidest one:

2 updates to system packages are available

When I open the updates there's just one updates and its already installed:

 kernel-devel   Development package for building kernel modules to match the kernel.    New version 2.6.18-194.32.1.el5         installed

Not too much bothering like the second one:

1.95 GB total, 403.00 MB used

Nice stats, isn't it? Yes but... Wrong!

Because the 403.00 MB used... is the available memory, not the used as "free" says:

# free -m
total       used       free     shared    buffers     cached
Mem:          2001       1597        403          0        188        821
-/+ buffers/cache:        587       1413
Swap:         4031         31       4000

How can I fix this? I mean... it's nice to go sshing here and there but sometimes I have no time to log in into SSH and check this datas manually... any workaround?

Here are some infos of the dedicated server:

I answer to my self:

http://www.virtualmin.com/node/9928

But why this happen only on some Dedicated Servers? I have other two all with Virtualmin and this is the first time I hit this? Any ideas?

The memory display is the same on my Ubuntu 10.04 system.

atop reports:

MEM | tot 1.4G | free 80.2M | cache 506.7M | buff 99.9M |

And Virtualmin reports:

Real memory 1.43 GB total, 783.54 MB used

Adding the free, cache and buffers, and subtracting from "total" in atop: 746.8 MB used, which roughly matches what Virtualmin reports as in-use. So I'd say this is not really a bug.

Yes, I agree... It's not exactly a bug but what about adding a new feature in Virtualmin?

Like, showing the free memory in two ways, one without explanation and one with explanation... I mean, something more detailed to avoid to fall in mistakes, I am always on run but yes I noticed it is not a problem, but what if some newbie wont understand what's going?

What I dont understand is that in another CentOS 5.5 server this is not happening...

By the way, again: I agree it's not a bug.
