      SERVER-66770 added some WiredTiger configurations to the config fuzzer. One of them is debug_mode=(rollback_error=N). This option forces WiredTiger to return rollback for every Nth operation. At the moment it triggers several bugs so I disabled it while checking in the change.

      Re-enable the option once all dependant bugs are resolved.

      Here is the relevant code in mongod_fuzzer_configs.py:

          # Rollback every Nth transaction. The values have been tuned after looking at how many
    # WiredTiger transactions happen per second for the config-fuzzed jstests.
    # The setting is trigerring bugs, disabled until they get resolved.
    # dbg_rollback_error = rng.choice([0, rng.randint(250, 1500)])
    dbg_rollback_error = 0
