rrdcached plugin: Failed to connect

After a new install of OMV5 on an x86 pc , all was going well, when i noticed this in the logs:

rrdcached plugin: Failed to connect to RRDCacheD at unix:/run/rrdcached.sock: Unable to connect to rrdcached: No such file or directory (status=2)

I did look through the threads and seems this was an old issue that was fixed.

Im not smart enough to figure this out, if anyone has some pointers please.

i googled a bit further and if i disable the monitoring slider the issue goes away.

oh well
