Error message in OH3 logfiles

Hello all,

has someone any idea, why I have such kind of error message in the logfile.
My OH3 runs und a PI4+ with OH 3.0.2-1 stable release:

[ERROR] [d4j.internal.RRD4jPersistenceService] - Could not create rrd4j database file ‘/var/lib/openhab/persistence/rrd4j/Gartentor_Uptime.rrd’: Read failed, file /var/lib/openhab/persistence/rrd4j/Gartentor_Uptime.rrd not mapped for I/O

More or less some of my Items has thoose messages, but all off them work fine so far.


Meanwhile I fixed it with a stable new installation and a backup-restore from the configuration
