    Description

      When running the Oracle connector after a while (12-16 hours) it stops unexpectedly with ORA-00310 error. Until then it streams perfectly fine with a LagFromSource of ~3-6 seconds.

      We are running Oracle 12c (12.2.0.1.181016) with 2 node (RAC), one thread per instance as well as 5 groups per instance (10 in total).

      Caused by: java.sql.SQLException: ORA-00310: archived log contains sequence 67140; sequence 67135 required
