RC30: panic: runtime error: index out of range when insert data points

[fffw]

I installed it on Mac through brew install influxdb -devel which should be https://github.com/influxdb/influxdb/archive/v0.9.0-rc30.tar.gz

Server panics after tens of writes when I trying the example code of https://github.com/influxdb/influxdb/tree/master/client, code snippet as below:

    bps := client.BatchPoints{
        Points:          pts,
        Database:        MyDB,
        RetentionPolicy: "default",
    }
    start := time.Now()
    _, err := con.Write(bps)
    if err != nil {
        log.Fatalf("Write error: %s", err)
    }

Detailed stack trace.

@fffw this looks like it was trying to run a query - were you issuing queries against the database at the same time? if so, can you send the query that caused this?

[fffw]

@toddboom Below are match lines in .influx_history and influxd logs before it panics. If it's a query that triggers the panic, it should be that stupid count().

select * from sonar
select count(loadTime) from sonar
select count() from sonar <---
