I am updating QLI records with Data loader, during the update I receive thesr error messages by email:

Apex script unhandled exception by user/organization: 00XXXXXXXX/00XXXXXXXX

Failed to process Queueable job for class SBQQ.QueueableCalculatorService for job ID 707XXXXXXdeHKt.

caused by: SBQQ.QuoteService.QuoteServiceException: unable to obtain exclusive access to this record or 5 records: a545b000001MWu6AAG,a545b000001MAnLAAW,a545b000000VlCtAAK,a545b000001MAmwAAG,a545b000001MFBfAAO

Anone could help me to figure it out what is the thing that is triggering the error?
