BUG #: 103075 (SQLBUG_70)
Under some rare conditions, SQL Server may report the following error message in the error log when it processes a query that includes a large, long running sort operation:
2003-02-10 17:02:54.39 ods The Scheduler 2 appears to be hung. PSS 0x5F8B3110, EC 0x5F8B32C0, UMS Context 0x050D07D8
This error message may be repeated in the error log as frequently as one time per minute, while the query is running. In some cases, the error message may also be accompanied by other symptoms. For example, SQL Server might be slow to respond to other requests. After the query completes, the server will generally return to normal operation.
A sort operation that triggers this issue may occur as a result of various Transact-SQL commands including an ORDER BY clause, a MERGE JOIN operation, or the creation of an index.
