      Description

      There was an automated test failure with the symptom:

        28: table, row-store (158 seconds)
      [1508303775:986736][17441:0x3fff82fff1b0], t, WT_SESSION.commit_transaction: commit timestamp 56bd4 older than oldest timestamp: Invalid argument
      [1508303775:986799][17441:0x3fffa4fff1b0], t, WT_SESSION.commit_transaction: commit timestamp 56bd5 older than oldest timestamp: Invalid argument
      [1508303775:988035][17441:0x3fff76fff1b0], t, WT_SESSION.commit_transaction: commit timestamp 56bd6 older than oldest timestamp: Invalid argument
      [1508303775:988156][17441:0x3fff167ff1b0], t, WT_SESSION.commit_transaction: commit timestamp 56bd7 older than oldest timestamp: Invalid argument
      

      Note that the oldest timestamp here is reported as Invalid argument - so maybe this is a startup race in test/format itself. That's made more likely since the failure happened on PPC - which is very parallel slow machine.

      The configuration that failed is:
