When i use argMaxIf function ，sometimes there will be problems.To be more precise, when I use a smaller amount of data, say 15,000,000 rows of data, I don't get this problem, but when I continue to insert 5,000,000 rows of data, the query sql reports the following error.
When divided into three sql ,three sql separate query HL_LOCK_TYPE,HL_LOCK_STATE,HL_BLOCKEDBY_INT_ID these three fields, is also no problem.
thanks

logs are below:
