A failure occurs because of this unexpected output:
[1752169866:908160][4560:0xfffff7ff54c0], test_checkpoint_snapshot01.test_checkpoint_snapshot01.test_checkpoint_snapshot(row_string), file:WiredTigerShared.wt_stable, close_ckpt: [WT_VERB_READ][NOTICE]: retry #0 for page_id 101, lsn 4, checkpoint_id 1, reconciliation_id 0, size 63, checksum 17e9acd4 [1752169866:918258][4560:0xfffff7ff54c0], test_checkpoint_snapshot01.test_checkpoint_snapshot01.test_checkpoint_snapshot(row_string), file:WiredTigerShared.wt_stable, close_ckpt: [WT_VERB_READ][NOTICE]: retry #1 for page_id 101, lsn 4, checkpoint_id 1, reconciliation_id 0, size 63, checksum 17e9acd4
(lots of retries). The test does some stuff in a connection, then checkpoints, then copies the home directory to RESTART, and opens another connection on RESTART. When the RESTART connection closes, it tries to checkpoint a file that is apparently closed, because it is opening the file and cannot read a page (presumably the root page).
Here's a stack trace:
