Now that you have mentioned it I do see the following error in the logs
2019-12-02T18:24:40+0000 [stdout#info] u"DBBase._rollback: exception in session.rollback(): (MySQLdb._exceptions.OperationalError) (2006, 'MySQL server has gone away')\n(Background on this error at:

We are running a cluster and once we hit this error on one node, other nodes also run into a problem with an invalid transaction
