Like this? diff --git a/src/test/isolation/specs/stats.spec b/src/test/isolation/specs/stats.spec index be4ae1f4ff..70be29b207 100644 --- a/src/test/isolation/specs/stats.spec +++ b/src/test/isolation/specs/stats.spec @@ -562,8 +562,9 @@ permutation s1_table_insert_k1 # should be counted s1_table_update_k1 # dito s1_prepare_a + s1_ff s2_commit_prepared_a - s1_ff s2_ff + s2_ff s1_table_stats # S1 prepares, S1 aborts prepared There's some fallout in the expected-file, of course, but this does seem to fix it (20 consecutive successful runs now at 100/2).
