BUG #: 57806 (SQLBUG_70)
A complex data modification query (an insert, update or delete) on a table that has multiple non-clustered indexes, which are based on some of the same columns, might cause the following error message to occur on the client during the compilation of the query:
Server: Msg 8624, Level 16, State 1 Internal SQL Server error.
If this error message occurs, the query does not run.
To work around this behavior, you can try the following:
Rearrange and remove redundant indexes on the affected table.
If it is possible that parts of the query are run in parallel, use the MAXDOP 1 query hint to prevent parallelism, which can prevent the error message.
Microsoft has confirmed this to be a problem in SQL Server 7.0 Service Pack 2. This problem has been corrected in U.S. Service Pack 3 for Microsoft SQL Server 7.0 Service Pack 2.
