SYMPTOMS
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.
