The information in this article applies to:
 * Microsoft SQL Server version 4.2 for OS/2

BUG# OS/2: 1890 (4.2)

SYMPTOMS
An unexpectedly large number of client connections to SQL Server may be observed using the sp_who command or performance monitor. Many of the clients shown by sp_who have rebooted or otherwise terminated their client applications. sp_who will show these clients to be blocked on one or more other client processes.

CAUSE
If a client connection is blocked by a lock held by another process and the client's connection to SQL server is abnormally broken (for example, network problems, client GP fault, or client reboot), the spid used by that client will not be freed until the blocking process releases its locks.

WORKAROUND
Clients should be sure to terminate their connection to SQL Server. Applications should cancel long running queries and, if necessary, explicitly close connections to SQL Server. This will tend to discourage users from rebooting or terminating applications taking an extended period of time to process SQL commands.

STATUS
Microsoft has confirmed this to be a problem in SQL Server version 4.2 for OS/2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
