I’ve been starting to learn Influxdb (1.8.4) over the last few weeks. I have some data coming into Influx from Node Red and visualized with Grafana. Originally all was working well, but recently I’ve started to see my lowly RPi1 lock up after a few minutes consistently. I checked usage prior to one of these crashes and found that influxdb is using massive resources (typically 95% CPU) prior to lock.
If I move the SD over to my RPi3, I can disable Influxdb.service. When moved back to the RPi1 the system seems stable and no significant resource usage (as is expected). It sounds like queries can kill Influx pretty quickly, but I don’t think there should be any running since NR and Grafana are both disabled at this point.
I can remove and reinstall Influxdb to fix it, but not knowing what caused the issue that seems like a poor choice. I would likely have the issue again. The only thing I can think could have caused this issue is a recent update/upgrade I performed in Buster. It could be related or just coincidence though.
I’d appreciate any suggestions on what to check since I’m at a loss after reviewing as many threads and documents as seemed applicable without resolution.
