BUG# OS/2: 1695 (4.2)

= SYMPTOMS =

If a serious network error occurs while a site handler is active, and a Remote Procedure Call (RPC) is attempted across that site handler, future connections to the originating SQL Server may stop responding or hang. Current connections are unaffected. On some versions of SQL Server, one additional connection can be made before the new connections stop responding, and on others the problem starts with the next connection.

This problem can be replicated by disconnecting the network between two machines that have active site handlers. Initiate another RPC (such as server2…sp_who) and wait for the error to be reported. Now log in to the SQL Server that originated the RPC. If you are able to log in, log out and try again. Existing connections should be OK, however, every attempt to log in to the SQL Server should not respond.

= WORKAROUND =

If you are experiencing this problem, try setting the timeout parameter to False. This causes the site handler to quit after one minute of inactivity. This minimizes the amount of time the site handler is active. Because the problem only happens when a network error occurs, this may minimize the occurrence.

= STATUS =

Microsoft has confirmed this to be a problem in SQL Server versions 4.2 and 4.2a for OS/2. This problem was corrected in SQL Server version 4.2aK10. For more information, contact your primary support provider.
