BUG #: 355601 (SHILOH_BUGS)

SYMPTOMS

Starting with SQL Server 2000 Service Pack 1 (SP1), issuing a xp_stopmail stored procedure while other SQL Mail activities (xp_readmail, xp_deletemail, xp_findnextmsg, xp_sendmail) are running may lead to unexpected errors.

The unexpected errors that may occur include:
  • Memory leaks.
  • Unexpected MAPI error conditions.
  • MAPI spooler problems.
  • The overall stability of SQL Server can be compromised.

CAUSE

Internal reference count activity of the MAPI profile leads to an incorrect release of the MAPI interfaces during the xp_stopmail operation.

STATUS

Microsoft has confirmed that this is a problem in Microsoft SQL Server 2000 SP1.

This problem was first corrected in Microsoft SQL Server 2000 Service Pack 2.
