      Description

      The concurrency_simultaneous_replication_wiredtiger_cursor_sweeps test is failing with a couple of different symptoms.

      The shell command:

      python3 \
             buildscripts/resmoke.py --suites=concurrency_simultaneous_replication_wiredtiger_cursor_sweeps \
             --storageEngine=wiredTiger --continueOnFailure --installDir=dist-test/bin --jobs=1 \
             --mongodSetParameters='{enableIndexBuildCommitQuorum: false}' --shuffleMode=on \
             --storageEngineCacheSizeGB=1
      

      asserted in wt_rec_upd_select():

      311	    /*
      312	     * The checkpoint transaction is special. Make sure we never write metadata updates from a
      313	     * checkpoint in a concurrent session.
      314	     */
      315	    WT_ASSERT(session, !WT_IS_METADATA(session->dhandle) || upd == NULL ||
      316	        upd->txnid == WT_TXN_NONE || upd->txnid != S2C(session)->txn_global.checkpoint_state.id ||
