Hi, this one worked for me: https://confluence.atlassian.com/jirakb/how-to-remove-duplicate-lexorank-fields-779159223.html

[Nic Brough -Adaptavist-]

This can happen when you've been re-ranking a lot and have used up too many spaces or put a huge distance between some issues.  It's more likely to happen when something has gone wrong with ranking somewhere, and you're hitting a broken one.

Best bet is to go through the options over at https://confluence.atlassian.com/jirakb/understand-the-lexorank-managment-page-in-jira-server-779159218.html

@Nic Brough -Adaptavist-  Thanks for your reply.

We are seeing this error after Re-indexing as part of weekly maintenance. 

[Nic Brough -Adaptavist-]

Generally, you don't reindex weekly, it should not be needed on a well-set-up Jira.

Have you worked through the steps on the document I gave?

[Anil]

Yes. I worked on that document yesterday. 

We have 14 fields in all.

Balance status check - Failed for most of the Fields.

Duplicate ranks check - Failed for half of the fields.

[Nic Brough -Adaptavist-]

And did you apply the fixes for those?

[Anil]

I did "balance"  to custom fields.  I am not sure how to fix.

[Nic Brough -Adaptavist-]

Did you read all the links in the "how to fix this" columns in the error message table?

[Anil]

Yes. 

The following error is in logs.:

Exception: 'Could not find suitable distance for rank.'
