FIX: Checkpoint Process Deadlock Results in Errors 603, 3314

ID: Q153954

The information in this article applies to:

Microsoft SQL Server version 6.5

SYMPTOMS

A stored procedure that performs the following actions:

creates a temporary table

inserts data into the table

creates a cursor for read-only access that is then used to update the contents of the temporary table

drops the cursor

drops the temporary table

can, if executed by multiple users, result in the Checkpoint Process being chosen as a deadlock victim (spid 3). In this case, the following message will come up three times:

Your server command (process id 3) was deadlocked with another process and has been chosen as a deadlock victim. Re-run your command.

The message will be followed by the following errors:

603: There are not enough system session descriptors available to run this query. The maximum number available to a process is %d. Split query and rerun.

3314: Error while undoing log row in database '%.*s'. %S_RID.

A thread-level Access Violation will also be displayed.

If you run sp_who prior to receiving 1105 errors in tempdb, the Checkpoint Process is not present, and if the client processes continue to run, the result is that tempdb eventually fills because the log is not being truncated.
