Druid query exception on MultipleSpecificSegmentSpec

We are running a query to druid 0.15.1-incubating

Query is run with druid sql

In this case query is run every 15 minutes and data ingestion is done with kafka

Strange thing is that this query is not failing allways, it just eventually fails.

Attached you can find two different log errors that we get when this query fails.

druid_error_1.log – more often

druid_error_2.log – les often and seems like previous one plus error with query=SegmentMetadataQuery

Please let us know what could be happening with this query execution.

Thanks in advance
