After roughly 24 hours of moderate DB load, "No such column" errors on Aurora

We are facing a issue that has only cropped up recently in correlation with increased traffic.

About 24 hours after our server restart, we begin to receive a large number of "No such column" exceptions

Upon some investigation, it seems some of the queries the Aurora database is responding, to not correlate to the actual query sent. For example, the query requesting "time_card_id" is defined as

{{ String sqlString = "select tc.time_card_id as time_card_id "
+ "from time_card tc "
+ "left join company c on c.company_id = tc.company_id "
+ "where tc.company_id = ? and tc.end_time is null";}}

and yet the column array the exception is indicating "time_card_id" has to be in, seems to be the columns of a completely different table corresponding to a completely different query. The above query works flawlessly for the first 24 hours.

Our connection string is

jdbc:mariadb:aurora://hostname/dbname
we have also tried

jdbc:mariadb:aurora://hostname/dbname?useBatchMultiSend=false&usePipelineAuth=false
as well as

jdbc:mysql://hostname/dbname?useBatchMultiSend=false&usePipelineAuth=false
