In the OA database:

plesk=> SELECT ds_id,dom_id,dom_name FROM  iis_addons  WHERE srv_id=1111;
 ds_id | dom_id |        dom_name
-------+--------+------------------------
 10001 | 11111  | domain.com

plesk=> select count(*) from domains where domain_id = 11111;
 count
-------
     0

Cause

Most likely the domain was removed from OA while the task was being processed, thus creating a database inconsistency.

Resolution

This issue is reported to the OA maintenance team as POA-99553: "Domain could be deleted while creating of a virtual web server bound to it". Please contact your Account Manager or Pooled Technical Associates team (pta@odin.com) to trace the status of the issue.

As a workaround the task should be canceled and the virtual web server should be recreated from scratch, if required.
