Index build stuck in catchup phase during rebalance

Following indexes are in Moving state :

• idx1_icZ3fb8q (replica 2) ON `bucket6`.`scope_3`.`coll_2`
• `idx1_p9nFB` ON `bucket6`.`scope_4`.`coll_4`
• `idx3_XgGg` (replica 2) ON `bucket6`.`scope_2`.`coll_0

Attached is the output of getIndexStatus [[^172.23.96.254_gis.json]].

The following logs are from 10/27 ~3 PM PST, which is ~9 hrs after the rebalance started. Let me know if you need logs from before or after this time.
