Row Lock Error - Updating the Picklist values in the Customer field and RecordTypes

[kongarara]

Hi Team,

We are seeing issues with MetaDataService class while adding a picklist value to a custom field and saving it to a record type. Adding picklist value is successful if there is no further action, saving it to a record type.
Also, it is working as expected when updating the custom objects and record types with fewer picklist values, but it is failing with objects having more custom fields, record types, and business processes in our Org.

Thanks,
