    Description

      While working on WT-9079 I ran a patch test for MongoDB. Though the changes for WT-9079 are on ARM, I saw a duplicate key error on x86. I am filing this ticket to have a look at the failure and see if it merits an investigation.

      Here is the error signature:

      [js_test:resharding_histogram_metrics] BulkWriteError({
      		 
      [js_test:resharding_histogram_metrics] 	"writeErrors" : [
      		 
      [js_test:resharding_histogram_metrics] 		{
