LZ4 decompression error

[mhajdu]

Hello. We have an openstack virtualization with ceilometer on each host. Gnocchi is running on a separate VM. Almost a week ago we were moving disk of a VM running gnocchi to another storage solution, but everything looked ok from the VM perspective. However we are getting following error in /var/log/gnocchi/gnocchi-metricd.log. I came to conclusion that only memory usage data is missing for all virtual machines, CPU is working ok. We are using gnocchi version 4.4.1 from repository cloud-archive:yoga. I have no idea how to reproduce the problem, but even when I made a new VM and removed all incoming data the errors still persists.

Any help would be much appreciated, thank you.
