VPS - stable?

Can anybody say anything about stability of the VPS platform? (especially software-part)

After a couple of days without rebooting my df -k gives the following info:

[root@vps /]# df -k
Filesystem 1K-blocks Used Available Use% Mounton
/dev/hdv1 126922044 29163896 91310864 25% /

This is strange, looks like account has 126GB of space and 91Gb free space ?( . However it’s a clean vps, no apps yet, and hsphere reports 413MB of total 800MB space in use…

Don’t quote me, but I think that’s because of the operating system / base files…?

I have disabled a few utilities to keep VPS stable(until next production release of the VPS), but will surely see if this can be fixed manually.
