Hi, On InfluxDB, I'm getting "panic:runtime error: index out of range" every time I run the "SHOW TAG VALUES FROM unbound WITH KEY = clientip WHERE sysName =~ /$hostname/" query from Grafana. And I also get it using the influx shell.
I've tried various things, like giving more resources (via login.conf), setting up various log level to identify whats wrong, erase the database and start from scratch, manually insert data in some other database. I can't solve this problem. Even giving more RAM to the VM doesn't help. I thought it could be an issue with bad data or badly stored data so I configured my feeds to fill both my actual instance and new ones I just created. On a fresh influxdb instance in an OpenBSD VM: same issue. On a fresh influxdb instance in a Linux Ubuntu VM: the error disappears and the query gets the correct answers. Find attached the complete log. Any ideas? Thanks.
