I came across a bug in InfluxDb 2.2 that causes the service to crash with a segmentation fault when aborting a query. I described the details in Influx’ GitHub issues list: InfluxDB v2.2.0 SegFault on aborting query. · Issue #23324 · influxdata/influxdb · GitHub
I wasn’t sure if that list is regularly checked, so I wanted to bring it to your attention here as well.
