Interesting thing happened with proxmox 1.4. (on host5)
I had reinstalled on the same old hardware that we had previously 1.3 version as a backup server and now when I was copying files from another host8 (also v1.4) with command...
scp *.gz host5:/var/lib/vz/templates/cache

And in the middle of a big template file the new proxmox version at the other end on host5 saiz... pooffff....

I logged in to check host5 and it seemed to work fine, except I could not get to /var/lib/vz/ dir.
I checked /var/log/syslog and it said

The only thing different on that server now is that proxmox is installed on 1TB HD instead the old 500Gb.
