• Use your database native transaction monitor to see if OpenLink? drivers are locked in pending transactions. OpenLink? drivers cannot disconnect from a database while they are still engaged in transactions.
  
• Ensure that your application does not enforce manual commits. Use of manual commit may encourage the behavior described above.
  
• Check the database native error logs for failures that may contribute to this problem.
  
• Create a client-side ODBC trace. Examine the trace to ensure that the application sends the proper sequence of SQLFree()s and SQLDisconnect()s to the driver.
  
• Ensure OpenLink? 's Progress Single-Tier drivers establish sockets-based connections to Progress. A Progress shared memory library bug causes failures to disconnect.
  
• Contact OpenLink? Product Support, if you use Progress 91C or 91D. OpenLink? is working to resolve occurrences of lingering agents that are not associated with the shared memory bug.
