No "summary stat" for only one VM

[Balanca]

Hi forum members,

I use Proxmox 4 for personal use. Zero problem except this little one, so congrat for the great job!

For one virtual machine, in the "Summary" tab, I have no CPU/mem/net/disk graphic stats. I only have a missing-image-icon.
Other VM don't exhibit the problem.

Stop/start the VM did not solve the problem.
Neither restarting the host.
I then deleted the virtual machine, and recreated it with the same ID : same problem again.
If I recreate whaterver VM with this ID I don't have the graphical stats. If a move it to another ID I have the stats.

I suspect this is a problem inside the stat redering subsystem, but I don't know where to search.
Any idea to solve this minimal anoyance ?
Or hints to find where the stat data is stored, and the way they are extracted ?

What ID exactly?

What ID exactly?

103

And file permission on /var/lib/rrdcached/db/pve2-vm/103 are OK (compare with other files)? Maybe the file is damaged, so it may help if you simply remove the file (should be automatically re-created).

The file was zero bytes long, untouched since several weeks.
I deleted it and the graphical stats worked immediatly.

Thanks!
