Read failure on LOBs, probably due to read uncommitted isolation level, or nolock scans. Microsoft provided the following explanation of the 7886 error, and a condition when this error may be returned by SQL Server: By default, the IS database libraries, when communicating with Microsoft SQL, uses READ UNCOMMITTED isolation level for transactions. Process Engine 4.5.1 relies on the Image Services (IS) 4.1.2 database libraries to communicate with and execute transactions in the database. This can occur on Microsoft SQL Server 2003 or 2008.
A common cause for this is if the application is running in READ UNCOMMITTED isolation level. Microsoft SQL Server will log a corresponding entry in the SQL Server error logĪ read operation on a large object failed while sending data to the client.
