Major - P3 While running the CONFIG from WT-5169 to try to reproduce the data mismatch, on two machines, both my AWS instance and kodkod-aws, both hit the same assertion:
[1570714095:788674][3319:0x7f7fd37fe700], t, file:wt.wt, WT_SESSION.truncate: __wt_delete_page, 113: ref->page_del->txnid == WT_TXN_ABORTED [1570714095:788716][3319:0x7f7fd37fe700], t, file:wt.wt, WT_SESSION.truncate: __wt_abort, 28: aborting WiredTiger library
This is running a recent develop changeset 2707680 from Oct 9.
