Research direction

Start by reproducing the primary-to-standby switch and the internal-table queries on seekdb 1.2.0.0, collecting the diagnostics associated with error 4012. Trace where the standby operation and internal-table access report that error; done means both operations complete without persistent 4012 failures.
