QBDL error CreatePaymentFromKC resulted in error at line X. Connection is busy with results for another command

This can be caused by KC and QB losing connection when performing the sync.  It can happen when syncing a long date range or a large number of invoices and receipts.


In KC, click on Utilities, QuickBooks DirectSync and do the sync again for this date and see if it will sync now.  


Please note:  KC will not resync any invoices/receipts that have already been synced to QB so it will try to sync only this item(s) that failed.
