Sporadic problems with InfluxDB

Hi all,
my setup is rather stable (3.2) running for weeks but from time to time InfuxDB (1.8.6) seems to conflict with Openhab. I get notified as soon as i do not see any graphs (basic graph, not grafana) in the GUI…

Looking into the logs i see a lot of errors. To me it looks like InfluxDB does have problems with openhab to connect. Does anyone else experience such behaviour? After a reboot all is fine again. Thanks for your thoughts. Norbert
