Continuous query skipping measurements

Store
1

Hi.

I have the following retention policies on my Telegraf database.

name         duration  shardGroupDuration replicaN default
----         --------  ------------------ -------- -------
autogen      168h0m0s  12h0m0s            1        true
30days5min   720h0m0s  24h0m0s            1        false

and use this continuous query to downsample the data:

name: telegraf
name      query
----      -----
cq_5m_avg CREATE CONTINUOUS QUERY cq_5m_avg ON telegraf BEGIN SELECT mean(*) INTO telegraf."30days5min".:MEASUREMENT FROM telegraf.autogen./.*/ GROUP BY time(5m), * END

This is working perfectly except for two, of the in total 50, measurements are missing from the 30days5min RP

I haven’t found any errors in the logs, I’ve tried dropping and recreating the CQ, but to no avail.

Any hints or tips would be highly appreciated.

Thanks,
Morten

UPDATE:
To try and narrow it down a little. Running this query manually works:
SELECT mean(*) INTO telegraf.oneyear.cloudwatch_aws_rds FROM telegraf.autogen.cloudwatch_aws_rds GROUP BY time(5m), *

Running the exact same query in a CQ does not:
CREATE CONTINUOUS QUERY rds_5m_avg ON telegraf BEGIN SELECT mean(*) INTO telegraf.oneyear.cloudwatch_aws_rds FROM telegraf.autogen.cloudwatch_aws_rds GROUP BY time(5m), * END
