> When multiple clients get index write failures, they may attempt to transition to PENDING_DISABLE
concurrently.  A race condition can cause one to exhaust its retries first and transition
the index to DISABLE, and another client to then attempt to transition from DISABLE to PENDING_DISABLE.
 Currently this is causing an exception to get thrown, leading to the KillServerOnFailurePolicy
getting activated.
